A gun as early as yours would not have a screw slot on the hinge pin. It is a straight 1pc. pin that is pressed in.

The barrels on your gun are Twist steel and should be blackened in Black/white finish, not rust blued all black.

Stocks for 1-1/2 and 2 frame guns are considered interchangeable from a basic dimensional standpoint.

The proper wood for a PH grade would be American Walnut with some figure, but not a lot.

Obviously the splinter forend is the correct style. Anything other than that would not be originally and then you are not really "restoring" it, but building a custom gun to work liking. I would keep the splinter FE on it.
