More AMG Unknowns

Another post in the continuing series of AMG models without a name.  As usual, any help in identifying them would be much appreciated. 

This one has a nice slim build and a great butt.   Follower Guido says this is Gary Bolen from Physique Pictorial Vol. 14 No. 3, dated February, 1965.

A couple of guys who look familiar to me.  It might be the Skants underwear.  :) 

This guy looks great in the AMG pool  Note the extensive tattoos.  I can't say I've seen him elsewhere, though. 

Same guy as the previous post joined by yet another model I don't know. 

Cute.  

Nice plump rump in the mirror. 

An "all natural" model most likely from the 1970s.
