Title: Model F or Model M buckling spring typewriter?

Hey guys, found this just now at the thrift store.

It feels nothing like my Model M, sounds more like an F. And I think I spy a PCB rather than membranes.

If anyone could identify it for me that would be cool. I also doubt this is easy to get to work on a PC at all.

Take off a keycap and shine a flashlight down the barrel, you should be able to see it for yourself :) .

To me, the defining quality of Model Fs is the layers of plates under tension and compression that give it "life"

A Model F has a metal front plate and individual barrels, and a metal back plate with the PCB mated to it.

In my opinion, this is a Model M with an alternate switching layer.

Model F pivot plates ("flippers") would enhance an argument for it being more Model-F-like, while the smaller Model M style would make it an M for certain.

In my opinion.

I am incline to believe you, but it feels so much different than my Model M. Granted my Model M is missing a number of rivets.
