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

The action appears to be the same as my custom 40-70. Mine is a Remington RB from a Sweedish military rifle.
