The butt plate is the Stevens #2 Schuetzen. It does have the same inletting and is the same butt stock as the #1 Sporting but, it's a prong butt plate. It was standard on the #45 model with up to #2 or #3 barrel. 

I believe it was for youthfull or lady shooters, as it's a bit small for grown men.

The #3 Butt stock and #3 Schuetzen butt plate was for the heavier barrel rifles.

The #2 & #3 are pictured.
