Remington 1903 Stock ??'s

[Mike Haas]

I have a 1903 Remington Stock. Not 03-A3. I recall a topic (perhaps the old Culver Forum?) about the holes drilled in the Butt of 1903 stocks.
Obviously one was necessary for the Oiler Kit directly in line with the Buttplate Trap.
My stock has two (2) holes. Is the 2nd hole a "Lightening Hole" and does the presence of Two (2) holes help to date the stock? Please refresh my memory.

The buttplate is IMO, original to the stock. The Trap Door is marked "R' as well as is the buttplate itself. Perhaps this info will help to "date" the stock.
