I've never seen a store brand mid arch chassis Sunbeam before. That's a new one for me.

The only full cranks I have found in the last few years have been the SPFC, one alloy base Mustang and three steel base models.
You managed to find two cup starter full cranks in a matter of days.

Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
