Ha! My 35mm SLRs from the 60s and 70s are still going strong, and they don't even need batteries!
My oldest working camera is a Kodak folder that used 130 film (fuzzy memory but that is what I recall).
Probably made late 20’s to early 30’s.
Edit: Sorry about the thread drag. We were discussing not so new micro 4:3.
