Yakolev Ya-7 (AIR-7) Found an I-26 prototype and it had the same general line so went backwards to try to find this one....never thought this one would have been produced in 1932-1933 though
Finally found it; it would appear to be the prototype KhAI-5-1 designed by I.G.Neman By the way thanks for the clue
You got it - I think the twin 76mm recoilless guns sounds like a great idea - shame they couldn't get it to work safely. Your turn
