Thanks for the comments Terry. Not going to worry about the tail. With regards to the beaufighter nose, would I glue the NFII nose to the Mossie and then cut and graft the beaufight nose(which I already have as well) nose on at the appropriate width?
Yep, that's the idea. You'd need to blend it in and probably widen it in parts, using Milliput or similar, but should be straightforward. Without checking scale plans, it would probably work well if the Beau nose was turned upside down. Do you need, scale plans? If so, PM me an e-mail address and I'll see if I can find the right ones for you.
Good stuff Evan. You ought to put a notice in front of the completed model of the 'Myrt', describing that it came from the designer's nephew - a unique display piece if ever there was one !
