Recently picked up a model 722 early 50's vintage which didn't have a front sight. The barrel has 3 holes where the ramp should go but pics I've need of replacement ramps only show 1 bolt hole for attachment.

I realize an aftermarket front ramp may have been installed but the rear sight looks original. Also, parts diagrams found online list 2 ramp pins required although the front sight appears to dovetail into the ramp. Do the pins fit into the barrel as alignment aid?. What else would they be for?
