I have a Jemco/Marks Models Master Scale P-51B-D unstarted kit which is a very very rare item now. It comes in 2 boxes, Box 1 is heavy & is full of stick, ply, sheet balsa & Plans. Box 2 is light but big & has lots of plastic parts & three types of canopies for the B, C & D model. Fortunately I have two such boxes (box 2) so you will get plenty of plastic parts in spare. Both Box 2 include all plastic parts for the canopy kit. There are gear doors, dummy tanks, cowl etc. etc. There are 2 sets of Plans - Original & a Scanned copy. Original Plans are 7 out of 8 sheets. Scanned copy is all 8 sheets. Original Plans have faded slightly but still 100% usable. The canopies in Box 2(2) are broken from the sides but from places that are discarded after cutting - so this will not effect the building at all. As it is there are 2 canopies of Type B & C each. Canopy type D has a small depression on the top that may be corrected by applying heat & giving some pressure.
Model Specs are: Span: 71 Length: 62 Engine: .60~.90 Channels: 6~8 Weight: 10~12 Lbs Scale: 1.92in = 1 ft.
I can email you more photos. I am also open to any further questions.
