I can’t offer an answer to which lock this is, but I’m not sure it’s either of the two mentioned. Did Clark make any locks other than the Durs Egg? Because I don’t think the lock on this pistol is that one anyway. Of course I could be wrong, but Clark’s Durs Egg Lock is a dead ringer for the L&R Durs Egg. They’re both copied from the same original.
I’d like to know what lock this is also, I t’s certainly nice looking.
