The kit and its assembly:
This is the third incarnation of a whif that I have built some time ago for a Battle of Britain Group Build at whatifmodellers.com. This fictional machine – or better: its model – is based on a profile drawing conceived by fellow forum member nighthunter: an Avia B.135, outfitted with a Merlin engine, a ventral radiator in the style of a Hawker Hurricane, and with RAF markings. It was IIRC a nameless design, so that I created my own for it: the Avro 675 Swallow, inspired by the bird's slender wing and body that somehow resonates in the clean B.35 lines (at least for me).
I’ve already built two of these fictional aircraft as early WWII RAF fighters, but there was still potential in the basic concept – primarily as a canvas for the unusual livery (see below). The basis became, once again, the vintage KP Models B.35 fighter with a fixed landing gear. It’s a sleek and pretty aircraft, but the kit’s quality is rather so-so (the molds date back to 1974). Details are quite good, though, especially on the exterior, you get a mix of engraved and raised surface details. But the kit’s fit is mediocre at best, there is lots of flash and the interior is quite bleak. But, with some effort, things can be mended.
Many donation parts for the Swallow, beyond the Merlin engine, propeller and (underwing) radiator, and pitot, were taken in this case from a Revell 1:72 Spitfire Mk. V. Inside of the cockpit I used more Spitfire donor material, namely the floor, dashboard, seat and rear bulkhead/headrest with a radio set. The blurry, single-piece canopy was cut into three pieces for optional open display on the ground, but this was not a smart move since the material turned out to be very thin and, even worse, brittle – cracks were the unfortunate result.
New landing gear wells had to be carved out of the massive lower wing halves. Since the original drawn Swallow profile did not indicate the intended landing gear design, I went for an inward-retracting solution, using parts from the Spitfire and just mounted them these “the other way around”. Due to the oil cooler in one of the wing roots, though, the stance ended up a little wide, but it’s acceptable and I stuck to this solution as I already used it on former Swallow builds, too. But now I know why the real-world B.135 prototype had its landing gear retract outwards – it makes more sense from an engineering point of view.
The Merlin fitted very well onto the B.35 fuselage, diameter and shape are a very good match, even though there’s a small gap to bridge – but that’s nothing that could not be mended with a bit of 2C putty and PSR. A styrene tube inside of the donor engine holds a styrene pipe for a long metal axis with the propeller, so that it can spin freely. The large chin fairing for a dust filter is a transplant from an AZ Models Spitfire, it helps hide the ventral engine/fuselage intersection and adds another small twist to this fictional aircraft. From the same source came the exhaust stacks, Revell’s OOB parts are less detailed and featured sinkholes, even though the latter would later hardly be recognizable.
With the dust filter the Swallow now looks really ugly in a side view, it has something P-40E-ish about it, and the additional bulge behind the radiator for the cameras (certainly not the best place, but the PR Hurricanes had a similar arrangement) does not make the profile any better!
Further small mods include anti-glare panels above and behind the exhaust stacks (simple 0.5 mm styrene sheet), and the small underwing flash bombs were scratched from styrene profile material.
