This is a generic version of silver (aluminum) doped Mossies which served in the China / Burma / India (CBI) theatre.
Problems were found with glue adhesion in the humidity, but it was actually the tropical heat that was the more immediate problem; the Australians did some experiments and found that painting the Mosquito silver reduced the heat inside the wings by a significant amount (appx. by 15 degrees during the daytime).
That’s why many photos appear to show metal Mosquitos. They were simply wooden wonders that had been painted silver.
Registration (Bort) letters are selectable. Pilots have white cotton coveralls.
