Hi Lawgger,
Thanks for posting your very nice looking stag 923. Your knife was made in the old Buck custom shop, the old custom shop was in operation for 1980 - 1993. As Armand said above one of the custom shop workers was Leroy Remer and he was most likely the man who made your knife, thus the LR on your blade. I took a look at the old BCCI news letters and Joe Houser put the manufacturing numbers for each model of knife made in the custom shop. There were 253 Medium Skinner's (model 923) made in the custom shop during it's operation. You can also try contacting Joe Houser at Buck and see if he can locate the exact date your knife was made.
Also, Oregon FYI that is not a tooth on the lanyard, it's an antler tip.
