The Martin Baltimore was a further development of the Martin Maryland.
While keeping the same design layout, the Baltimore was heavier, roomier
and was powered by larger engines than the Maryland. The first of these
was flown in June of 1941 and deliveries of 50 Baltimore I's and 100
Baltimore II's began soon after with the first reaching Britain in
October of 1941. Early models featured an armament of eleven 30 caliber
Browning machine guns, four in the wings, two in the rear dorsal
position (an open position in early models and a turret later), one in
the ventral hatch and four mounted in the belly mounted at an angle to
the rear as "scare" guns. The Mark I's were retained for use in
training squadrons while the Mark II's went to squadrons.
The bulk of the first order was made up of Mark III's which featured a
Boulton Paul hydraulically operated dorsal turret fitted with four 303
Brownings of British manufacture. The Lend-Lease aircraft, which had to
be initially ordered by the U.S. Army Air Corps, were given the
designation A-30, though all were delivered to the RAF. The first of
these was the Mark IIIA which differed from the Mark III in featuring
an electrically operated Martin dorsal turret of reduced profile
containing a pair of 50 caliber Brownings. 281 of these were delivered
followed by 294 A-30A's or Mark VI's which were similar to the IIIA.
The entire final order of 600, known to the Army Air Corps as A-30A's
but to the RAF as Mark V's featured 50 caliber wing guns and more
powerful Wright R-2600-29 engines. The first of these appeared in
December of 1942 and when production ended in May of 1944, 1,575
Baltimores had been built. Most of these were delivered directly to the
Middle East. Pilots generally liked the Baltimore, the main complaint
being that its narrow fuselage prevented crew members from being able
to move around during flight and more drastically made it almost
impossible for another crew member from taking over the controls should
the pilot be wounded. This was also the same problem that was found
with the Douglas Boston / Havoc series.
The Kit
The Classic Airframes kit
comes in a two part top open box typical of Classic Airframes with nice
artwork of a Baltimore flying over the pyramids. Inside the box there
is a large zip lock bag containing all but the clear parts and a
smaller bag with those. Inside the large bag is a smaller bag
containing the resin parts. The parts are molded in what has become
typical for CA a blue gray plastic. The parts feature recessed panel
lines that are fine and uniform. The parts have a semi gloss to flat
finish and there is some light flash on some of the parts. The control
surfaces are all fixed and feature very nicely rendered fabric detail.
Looking over the airframe parts I found no sink holes or other surface
blemishes. The kit can be made up as either an early model with an open
gun position or the later version with the Martin turret. The "scare"
gun locations are recessed into the rear fuselage and these would need
to be filled if building the later version. While the turret is nicely
rendered with resin parts only the guns are provided for the open
position which could use some additional detail. The main gear bays are
boxed in with a rather unusual piece that gets folded and dose have
some nice detail molded into it. The gear doors also feature recessed
rivet detail which is a nice change from ejector pin marks found on
many kits. The only ejector marks that will need to be addressed are
some towers on the inside of the fuselage. The props are the "build
them yourself" style which feature plastic blades and nice resin hubs.
The interior is very nicely done with a combination of plastic and
resin parts and even includes the radio operators position which will
all but disappear when the fuselage is closed. I would strongly suggest
replacing the tail wheel strut with a piece of brass or other suitable
wire as the supplied part is very delicate looking. It can be seen in
the forth photo down between the two fuselage tail sections. Altogether
there are 71
parts molded in gray. See photos below.
The resin parts supplied include both engines with separate cylinders,
propeller hubs crew seats, guns, cockpit side consoles, engine air
intakes, wheels, oil cooler inserts and instrument panel. The
instrument panel has some nice raised detail but no film or raised
parts for the instruments, just recesses which could use some
instrument decals in them. All these parts are molded in a dark gray
resin and were free of any bubbles or short shots. A couple pieces had
some light flash but it should clean up easily. altogether there are 53
resin parts. See photo below.
The clear parts are thin and relative clear and should look great after
a coat of future. The frame lines are raised which should help in
masking. There are a total of 10 clear parts for a kit total of 134
parts. See photo below.
The decals are very nice looking, thin, glossy, in register and the red
looks correct for British markings. The sheet provides markings for
four aircraft, one early and three late model. Two are in typical
British desert colors, one all black and one in RAF Coastal command
colors. See photo below.
The instructions are printed on two 8
1/2" x 14" size sheets printed on
both sides and folded to create 8 pages. The first page has a brief
history and specifications, the second page has an icon chart, paint
color key giving paint names only, and a parts map. The remaining pages
cover assembly. There is a separate sheet 8 1/2" x 11" that has the
marking and camouflage information. It should be noted that the engine
assembly instructions are in error. It has you assembling the back row
of cylinders with the connecting rods facing the front of the engine
which is wrong, they should face towards the rear.
Conclusions This looks to be a
really nice kit of a much overlooked aircraft. Like all Classic
Airframes kits one must take the time to clean up and test fit parts
before assembly but most reports indicate there are not major fit
problems to deal with. I would recommend the the kit to anyone with
some experience with limited run kits but not to beginners.

As with most aircraft the logical
place to start is the cockpit and interior as this needs to be done
before the fuselage can be assembled. This kit is no different. As I
had been forewarned that the various bulkheads were all over sized I
decided to address them before adding any of the small detail parts, so
diverging from the instructions I assembled all the floors and
bulkheads into one assembly, let it thoroughly set up then sanded every
thing to fit. I found that most of the bulkheads had a taper on the
edges to facilitate easy removal from the molds and I found that in
most cases sanding the edge till it was flat provide the relief
necessary to fit the fuselage. Once I was satisfied with the fit in the
fuselage I added all of the seats, consoles and other various details
supplied for the interior. I added some PE levers from my spares box as
I thought it would dress things up a bit. The pilot's seat location was
a bit ambiguous on the instructions so I used a pilot figure to
position it height wise. From the instruction sheet it looked like it
was setting on the floor but at that level the pilots eyes would have
been below the instrument panel. I added a few instrument decals to the
instrument panel and high lighted the raised detail with a silver
pencil. Seat belts and harnesses also came from the spares box. Once
every thing was installed I gave the visible interior parts a sludge
wash and it was ready to be inserted in the fuselage. See photos below.
One of the things I found after taking the above photos was that there
were glazings to fit into the openings behind the pilot. This makes
sense as it would otherwise become quite drafty, especially on the
versions with an open gun position. The instructions do not mention
them at all. One side seemed a bit larger than the other and one piece
seemed to fit better in one place than the other. I glued them in place
with clear parts cement then brushed them with future after they dried.
As usual when I went to assemble the fuselage I found that the entire
assembly seemed too long. If I positioned the rear bulkhead for the
radio room in a position to allow the turret to fit then the pilots
rear bulkhead sat forward of the fuselage opening and the floor for the
bombardere extended out beyond the edge of the nose glazing. It
appeared that the best fix for this would be to break the connection
where the pilots rear bulkhead met the radio room floor and reglue it
about an eigth of an inch back from where it was. This seemed to take
care of that issue. There are no locators for the interior on the
fuselage walls so I positioned it where I thought it should go and held
it in place with some silly putty and used some five minute epoxy to
attach it to the fuselage. Once this was set I glued the fuselage
halves together. There was a gap around the top of the pilots rear
bulkhead that would show through the canopy so I filled it with some
Magic Sculpt and when dry painted it.
