Some time ago I corresponded with John Craig about the George Miller A-10, because I had bought a semi kit online, which includes the fiberglass fuse and other parts, and the ribs & stringers for the wings and tailplanes.

He gave me a price on an A-10 kit that is exactly the same size as the GM A-10, but with foam wings instead of wood. He also gave me a parts list and was willing to sell spare parts for anything I needed on the GM plane.

I'm not saying he has THE molds, but he has a way to produce a fiberglass fuselage in that size.
