I'm aware this is the case. I'm going to an estate auction This weekend and a highway patrolman is listed as well as a 3 inch 60–10. Going to try to get the 60 for my wife, and interested in the highway patrolman if I can get it at a low enough price. Possibly to resell. Or at least that's my story to my spouse. My question, I've noticed on GunBroker that highway patrolman serial number appear to be on the frame inside the yoke, too. Is this the case with this model, or not? I don't think I'll be able to remove the grips at the auction.
