I have a Meikraft Models 1/72 Grumman FF-1. The kit will definately require all of my attention, but the large parts are actually not bad, although I will probably have to replace a lot of the small parts. It is the only 1/72 FF-1 kit I know of so it does at least give me a decent start. As Stephen says, these kits do make you appreciate what we have today when many limited run kits now challenge the quality of older mainstream kits.
I don't know if all of these were actually made but the instructions list the following kits from Meikraft:
Vought SB2U, Piper L-4, Albatros D.I/D.II, Seversky P-35/P-35A, Hansa-Brandenberg W.29, B.E.2c, Douglas D.558-1 Skystreak, and the Grumman FF-1.
There is a reference to the April 1988 issue of Skyways in the instructions, so the kit is not as ancient as I expected.
