Guy gave you good answers. Follow his advice to the letter and you will be fine.

I just want to add a couple points that might help your understanding.

1. This revolver is not in any sense a "Model 10." It is almost 30 years too old for that designation. It can be considered an ancestor to the Model 10, but in many ways it is quite different.

2. When the Model 10 was first shipped in 1958, one thing it retained from its ancestors was the right hand threads on the extractor rod. This was changed to left hand threads in 1961. So, any instructions you find for the Model 10 might say the threads are left hand. Ignore that and use the info provided by Wiregrassguy.
