That doesn’t appear right. Compare to a well used any original actuator WWII or earlier. Doubt one would see comparable marks or wear.
A long time ago I bought a new reproduction 1921 actuator from someone in CO, IIRC about 2006. Never made notes of who made it. With just a few rounds cycling through I noticed marks on the actuator, but not in the same area as you have, nor strikes like that. This one had very authentic knurling, think of the width of knurling on early Colt actuators. I happened to be at a shoot with Gordon Herigstad, we looked at it and filed away enough material to make sure it was not striking the receiver. This was NOT one of Doug Richardsons actuators. I shot thousands of rounds with that, it finally broke an ear about 4 or 5 years ago, I was pissed!
No comparable reproduction 1921 reproduction actuator that I have found other than having a knurled 1928 one milled down. The difference being primarily the look and band width of the knurling being different.
