I think all Model 60's were marked on the barrels as West German guns. However, although I'd like a little closer look at your barrel flats, the proofmark farthest left--looks like a leaf--certainly appears to me to be the Eckernforde proofmark, which would make it West German for sure, and the gun a Model 60. Quite a few of those did not have a Greener. For example, my Stoeger catalog (1961) shows the Model 60 without a Greener.
