Panher F....you are right and I was totally negligent in not checking references instead of relying on my own limited time with Shermans. The subject matter though, was the engine in the Firefly which was the Chrysler multibank. Along with Hunnicutt,(pg 550), Hogg & Weeks Enclopedia of Military Vehicles (pg 109) also states that most all Fireflys were made from M-4A4s. What threw a monkey wrench into this was the fact that YHR used an M-4A3 with VVSS for his,(as I did with my 1;18 scale Cent 21 sherman.) Not many A4s out there and it would be a major undertaking to extend the chasis and retain the lines etc. Since Fireflys were made until 1947, in theory, a few could have been made from a later A3, but by 1946-47 all Shermans had HVVS, except a very few NG units and a few M-4 105s with VVSS and a number of M-32 VTRs, which leaves YHR's great looking Sherman VC with out-of-era suspension, tracks and added protection tracks.

George Forty's M-4 Sherman lists three types of firefly, (pg 87-88) Sherman IIC,= M-4A1 with 17 pdr, Sherman IVC=M-4A3 with 17 pdr and Sherman VC= M-4A4, of which most were built. Unfortunately no additional dates, tech data or numbers are given other that a table of details on the Mk IV of Mk VII gun. Engine breakdown is on pg 95, with no correlation to any particular tanks. It would be interesting to learn about Firefly IVCs that were built, and when. No indication as to suspension was listed by Forty..

Nevertheless, YHR has a great looking Firefly with a lot of nice detailing. Leave the engine grills closed and don't crank it up and it'll sneak by OK.
