Thank you everyone for your replies and willingness to share.
Good points about having or not having separate manuals for each model makes sense.
At this point in time, I do not plan on disassembling it but in the future, who knows. I might work up the courage to do so.
I will check out the included links on manuals and parts lists.
I will take what has been shared to heart and not do anything that could ruin a fine piece.
And as this is my first revolver, do not be surprised if I post more questions!
Again, thanks for your help.
