Pretty sure the lens says "JSCO-GOTTINGEN" on the front (can't check it, since I left it at work). Wonder if "JSCO" is a different (cheaper?) line of lenses. It is a machined metal bodied lens- looks like aluminum. I will try to clean and lubricate the little bugger- I suspect that old grease is its biggest problem. Best used as a training item.
I mean to emphasize the "little" part. The lens contacts and focus drive are exposed when it is mounted on the camera. Thanks for confirming my first impressions.
