Italeri MiG 37B Ferret E (Soviet Stealth Fighter Concept) . . .

Any updates?

I think with some work, one of the F-19 canopies might work.

Hmm :

Based on the picture you might be able to either find something to suffice for the main canopy or make a mold and smash mold it. Fhe front three panes can be gotten from  the small box that Clips for office work come in. They are optically clear, fairly thin and polishable.

I dug through my stuff and I have the kits, but in 1/48 scale, not 1/72.

But my F-19 came with two canopies, a bubble one and a flat sided one. Does your F-19 include both styles? If so, you might be able to work one of them into the MiG cockpit.
