SA#935321 looks as if G&H did the work,rifle is circa 1921 and the parts fit the time frame.
The Lyman #48 is a shortened long shank which is correct ,long shanks had gone out of vogue
because of the stock breakage issue.The "WL3" bolt was started about that time frame.
The stain looks like "log wood" stain which would still be used on expensive rifle stocks.
It's application is quite time consuming and exacting.
