At least one of those is a Model M. The two piece keycap missing it's top is a dead giveaway. The area around the barrels on the pics with the missing keycaps looks quite plasticky as opposed to the shiny olive metal you'd expect on a Model F.
Bare in mind that early Model M 122-keys looked identical to their Model F predecessors, even down to the 'hat' keys usually associated with Model Fs.
