BTW, crane was the term used in the ad.
It really doesn't matter unless you are trying to order parts and don't find a "crain" listed. For some reason the manufactures have never been able to get together and use the same word to describe a particular part. The result is unnecessary confusion.
Some police departments no longer sell surplus guns, but instead either destroy them, or send them to a used parts company that strip them down, and then send back only the frame for destruction. For some reason this makes gun control advocates feel warm and fuzzy. :banghead:
The remaining parts are sometimes packaged and sold as a kit - often to buyers that don't realize that older revolvers (and some current ones) are not made up using so-called, "drop in" parts, except for such things as springs, screws, other parts that don't require hand fitting.
Your model 10-5 is a pretty rugged piece of machinery, and parts are unlikely to break. Replacement more often then not, is because a screw or something is dropped and lost when the gun is being disassembled or reassembled, or someone has tampered with the insides without knowing what they were doing.
Replacing a major component, such as a barrel or cylinder assembly should be done at the factory, or a qualified gunsmith (not many are). If you want some other small parts on hand (screws, springs, hammer & trigger assmeblies, rebound slide, cylinder bolt assembly + thumbpiece and nut, etc.) go to
