1/72 Airfix Bristol F2B converted to Tourer/Coupe

What does one do when in England? yes, one buys an old Airfix kit.
How old? look at the photos, 1957 vintage! a mold 55 years old to this date.
Man those Airfix -and successive re-incarnations- squeezed the pennies out of that mold.
What I want to do with it? you betcha. Convert it to a civil machine, likely some variation of the Bristol Tourer/Coupe.
History: At some point after the war it was realized that transporting people was much, much nicer than bombing then. This very painfully-obtained knowledge was not, however, kept in mind for a long time. The Bristol Tourer/Coupe was a direct derivative of the Bristol F2B. In that regard, many countries, like Japan, France and Germany were doing the same: hastily converting war leftovers for the incipient civil market, many times with the procedure of producing a “hunch” to protect the weary passengers against the elements.
I may refer you to two of my models:
-Hawa F.3 (in this very blog, and old post):

 -Hansa Brandenburg W.29 J-BCAL:
You could model a civil machine without modifying a single part of the Bristol Airfix kit, though. There were a couple of Canadian machines (G-CYBC / DP and at least one Spanish that flew the plane as it is represented in the kit (minus armament, of course).
Beware, since some of the other civil versions had different engines, cowls, radiators, rudder, passengers’ compartment covers, supplementary fuel tanks on the top wing, and minor details. Look at your photos, not even at drawings: photos.
Since I was looking more and more at some G-AUD_ civil versions I did some preliminary chopping, cleaning, filing, filling and sanding as per images. All the stitching was eliminated at this point, later to be replaced by other devices.
You can see in the building photos that some areas have been removed and the section corresponding to the passenger cabin altered to represent the increase in fuselage width that was incorporated in the real plane in order to accommodate the side-by-side seating arrangement. Not all Coupes/Tourers had this increase in width; again, check your photos. Some formers were cut, and the usual interior paraphernalia prepared for the cockpit and passenger cabin. Some external elements (augment rudder, different nose, hunch, top wing tanks, etc.) had to be scratched too.
As you can see in the images the major work was concentrated in two areas: the passenger cabin elements and the nose. The former is a complex area that need careful observation of the photos and accurate execution. Of special note is the transition from the former back of the pilot (which has a sort or triangular shape at the top) to the first passenger cabin former, which is quadrangular with round corners at the top, and leans forward.
The second area of effort as said was the nose. A wood master was prepared in order to vacuform the cowling. Engine, radiator and ancillary parts (like the oil tank) were scratched. The engine alone insumed about fifty individual parts. Again, attention needs to be paid to the sections’ transition, from firewall to radiator. At the firewall the top is rounded and the bottom straight, and that reverses at the radiator’s cross section.
Home-made decals were prepared: a bundle of “stitches’ strips” and black regs on white decal paper stock. More details related to the upper wing, control surfaces, ancillary parts, etc. were made; paint ensued with a home-made custom color of all sub-assemblies.

 



The fuselage bottom was cut out to allow for the curvature of this section

More chopping and some assembling, including a new, larger rudder adopted by some of the G-AUD_ versions
