...you have to buy the CMR model.
It is one of the best resin kit available, include the full interior and the best instruccions and information included.
It is posible to buy for 38 euros, maybe less.
This is my CMR S-38, splendid interior visible from the dorsal entry door
My second one could be the english in Los Alcazares because the colours is one of the standard Sikorsky factorie finish, I love resin model, in many aspects better material than plastic.
