no question that it's from a 127 / 27. I only get one photo. which shosw the part upside down . the other start to load then they just go away. fiddle or rectangular, that piece will be the same..
I'd watch ebay or just buy a machine for parts . like off goodwill or craigslist, but I wouldn't pay over $15.
The date given sounds like the patent date on some frames
