Went to a gun show in Portland and picked up an Old Timer, the model that looks like a buck 110. Saw Cut Delrin scales witha brass inlay that says "Old Timer", brass lined lanyard hole. If you hold the knife with the edge up, on the left brass bolster is a serial number "3526". On the left side of the tang is says "Schrade+" below that "U.S.A. 6-OT". On the bottom half of the blade is etched (?) in large letters "OTC" then "Commemorative" and below that "1997". Knife does not look like it was every sharpened or used. Came in a Schrade leather Belt pouch with the man embossed on the top hammering at an anvil and "Schrade" below him, also the snap has Schrade on it twice, and it looks like the pouch was never carried either. Would appreciate any information on this model, and if anyone knows what the OTC Commemorative 1997 was for. Thanks. PS I gave $15 for it.
