Short quiz: two Thompson barrels

[browningautorifle]

Well, I cheated. I had an earlyish 1928 with many early features. It had a Nickle bolt, and one piece ejector for instance. It was marked to the Bapty Movie Company...a vet bringback from Italy was numbered S68038. Although a Savage gun, a very elderly collector from Chicago/Portland told me it was made on the Colt machines. I've examined lots of them.
