M caliper identification

[Phrog]

Need help with dating these M calipers. If you can ID them please assist. TIA

The center and right could have come from about 1969 through about 1974.
No idea on the left one.

The far left caliper is a Carrera rear caliper with a piece of toilet paper in it's inlet If you only have one I might have a mate.

I'd need more detail on the front gussets on the others and it would help to see the tops but, Dave is pretty much spot on with the date range of those. Garden variety front M-Calipers.

Ooooooooops, sorry, just noticed the far right one has a fluid inlet on it's end. That's a rear M-Caliper (70-83). That being the case, the center one looks proportionate and is probably an early 914 front caliper (70-72.8).

Turn it over and please tell me more about the fasteners. M7 fasteners with a cap head (on the middle caliper) means it's an early 914 front caliper. They are cast from the same mold as the far right rear m-caliper but do not have spacers and have a larger 42mm piston (38mm on the far right one). If it has M7 11mm hex head bolt with dual bleeders, it's a later model 914 front caliper (73-76). Probably has VW cast into it somewhere as well.

The Carrera rear caliper is 84-88.

Hope that helps.
