I need help identifying brake calipers

[Chris Pomares]

Can someone help me identify 2 different sets of calipers. Both have a 3 inch bolt spacing. They came in a bulk purchase of parts.
Thanks, Chris

Vented rotor M calipers, front and rear.

What years and model 911's and maybe 69 912's? used these.

[76911S]

"These are the vented rotor M-Calipers that first showed up on the venerable 1967 911S. After a few years on the "S", Porsche decided all 911's should have vented rotors (1970 was the first year for vented rotors all around) and this caliper was the staple while the S received a new caliper based upon the alloy 908 caliper... the "S-Caliper" in 1969"

Assumming that they came off the same car, they can not be any earlier than the 1969 year model. Those were used from 1969 (optional) and were the standard calipers on all 911s from the 1971 cars thru 1975. No 912s ever got vented rotors (that I am aware of), not even the awsome 912Es of 1976.
