thanx, i think so, too. i sent the image album to kenn, maybe he can shed some better light on it.
Pretty sure there are few if any sporter parts on that rifle.
Check the width of the receiver, they are as follows;
#1-1/2 1.140" width, .205" walls. All were sporters, and had rotary extractors. Calibers .22rf to 44/40
#1 sporters 1.225" width, .240" walls. All were linear extractors. Calibers .22rf to 50/70
#1 military (black powder) 1.312" width, .290 walls. Early ones had linear extractors, later ones had rotary. I don't have info on the dozens of variations of military actions. There may be some variations in width between models but I am pretty sure none were ever as thin as the #1 sporters.
The only Rolling Blocks I've seen with the sling swivel holes in the trigger guard are the NY State, Springfield Contract, and the Norwegian.
the US Army Caliber 45-70 Cadet Rifle
used the 1 1/2 RB Action, fitted with socket bayonet and sling
From Konrad F Schreier Jr.'s book..Remington Rolling Block Firearms
The action appears to be the same as my custom 40-70. Mine is a Remington RB from a Sweedish military rifle.
