SR engine identification, Who knows?

Hi.
Could anybody tell me information about this SR engine? When and how long was this engine manufactured? Look at the position of the oil filler bolt!

Thats an engine for a "Spatz" since 1964. But the cap on the clutch isn´t right. There have to be a cap without the smaller cap.

Hi. Many thanks for your answer, I appreciate it, because my friend intends to buy this engine, but we could not identify it.
Chiers!
