This is a conversion of the Airfix 1/72 Lancaster to a York using the Czech Master convesion kit. The CM kit contains a 1 piece fuselage and various bits.
I am also using the Eduard photoetch flap set.

The conversion has you use the Airfix wings mated to the CM fuselage. I had to modify the wing roots to use the p/e flap set. I also had to modify the engine exhaust to get rid of the flame dampers and install the pipes the York used.
