Stan, Your gun is a Regular frame, by looking at the pictures and seeing the size of the lug and the long 2 screw trigger guard. As Dr. Drew said, first finding a stock is hard enough, even if you found a Regular frame stock it still might have to be inletted to your works. Even the low grade guns were hand fitted.
The bluing job on the receiver and side locks was redone, it was offered later in catalogs.
In buying the side locks complete for Numrich, they are Featherweight side locks and will not fit your frame.
In my opinion I would opt for fixing that stock. Does the stock fit together without gaps, is there any pieces of wood missing. If it goes together I'm sure it can be fixed. Getting a new stock made and checkered in a low grade walnut could run you $1,000+
