Identify a Gillette and other razor

Hello people,I recently found these razors in a flea market, a Gillette that I don't see provenance (only patents i see) and a Probak, that says Argentine industry and
doesn't have both tip teeth.
The heads are the same or very similar, I would like you to help me identify them, thanks and greetings from Buenos Aires, Argentina

Presumably the Gillette came out of the same factory which as I recall was a former Autostrop (Auto-Strop-Probak) factory prior to 1931. It's been my theory that the Short Comb design came from Autostrop people after the November '30 merger.

Another example of the Probak Short Comb Goodwill
