Well done S'land and Drawbarz. It is indeed the Ssimunek Kamaryt FK-1. Designed by Messrs Ssimunek and Kamaryt but actually built by Letov who used the name SK-1 Trempik. It made its appearance in the UK at PFA International Rally at Cranfield in 1983. It still flies today.
I would have accepted either name, so S'land, as you were first, you have control.
