Descriptive error on my part. When I wrote three, I should have stated, three Schrades. I'm a Gerber collector at heart and made an offer on a grab bag lot of knives to get the three Gerber's that I could identify. Most of the other knives turned out to be decent, including this 165, the sharpfinger and the LB7 that I have posted elsewhere. I've had virtually no experience with Schrade Old Timers and am enjoying learning about them. So, this is the only 165 I have and at the time, was not aware of the significance to the Walden stamp. Per the photo below, the knife was pretty dirty, but the blade profile is all there. This thing is incredibly stout and is shaving sharp. Oh, and no serial number on this one. Transitional?
