Hey everybody, I recently picked up an H&R 22 Special from 1929ish as a project gun. This is my first foray into restoring an old firearm, so this question is probably very basic and obvious to others. Some of the parts in the trigger mechanism are pretty worn out and it the cylinder doesn't reliably advance. I have read on forums like rimfirecentral that trigger parts for other H&R revolvers from this period are compatible across multiple calibers. Is this accurate? I know this model is the precursor to the 999, I haven't been able to confirm whether or not model 999 parts are compatible. The parts I believe that need to be replaced are the cylinder stop, lever and spring assembly, and possibly the trigger spring. Numrich has these in stock so I may just order them and give it a go.
