Lenses getting stuck

Which are the ones that get stuck. PKR and KR, and are there others too?

So people might sell the PKR or KR and say it's for Pentax, since it looks similar? I should watch out for it having an extra pin - any pics?

Just trying to not get one stuck if I am looking at old lenses.

theatre of noise: Ricoh Lenses On Pentax Cameras -- The Ricoh Pin Fix

This may help.

Not all Ricoh pins will get stuck. Some are made like the regular contacts on the lens and those lenses are easily removed. Others, the pin will drop into the AF screw drive and, well, you can find all kinds of horror stories. A lot of people selling these lenses may or may not be aware of the issue. Yes, they are K mountable but it's something you have to watch out for. Vivitar lenses that are made for Ricoh cameras (as a one size fits all type) may also get stuck.
