hi dave,
i think you might find that the 25 in the title refers to the roman
numerals XXV.
B was the designation for the bomber versions of the Mossie, therefore
the model Mossie pictured is a BXXV.
IE: Mosquito B Mk 25 : Improved version of the Mosquito B Mk XX Bomber
aircraft. Powered by two 1,620 hp (1,208 kW) Packard Merlin 225 piston
engines; 400 built.

Beyond the Mk XX, DHC switched to Arabic numerals to denote marks.
