I recently bought a Colt Official Police with the letters PLCB stamped in the butt of the frame. I assume means Pennsylvania Liqour Control Board. Anyway I always strip guns to clean them throughly, but am way more accustomed to Smith and Wessons. I am trying to remove the extractor rod from the crane. I can get it all the way down to removing the star and it looks like a collar in the barrel of the crane...with two slots in to turn out. Question? what is the name of the tool to remove this collar? and is it right or left hand thread? Am I correct in how am proceding to remove this extractor rod? I have two dective specials and a Colt Trooper MKIII. So this isn't my first Colt.
