Puch Cobra in Movies

The grey seems a pre-Cobra Par contre, la Yamaha bleue en arrière-plan est une FS 1 DX... the black one, leaning at the yamaha, is a Puch MS 50, called "Stangel-Puch" or "Postler-Moped", which means "postman's moped". the grey one is confusing me. engine and air-filter are style of MS and DS-time. "pre-cobra" should be the time of M 50 "sprinter", M50 racing and so on. they had a different layout and different engines. I think, the cobra came out 1977, monzas were before. :-)) m.
