Looking for some good old glass.

Never heard of it. Pentacon/Meyer Optik have a fine pedigree though. Maybe check out some garage sales. You may get lucky!

This thread can be closed because I got my lens!!!
I sound one with a 135mm f/2.8 OM mount for for $18 after shipping!!!
I bought the lens, a OM to EF adapter with FC chip (we'll see how well the FC chip works), and a EF rear cap. All of it together came to $29.23!!!
