All About Pocket Knives

Here is a Sharp Finger I picked up recently off ebay. Obviously it was an SFO for Guns & Ammo magazine (see shield). It has a carbon steel blade, but the most remarkable thing to me about this knife is the tang stamp.
It is a simple 2 line stamp: SCHRADE/U.S.A. I have seen this stamp before on a 154OT, but it is not often that this 2 line stamp shows.
Has anyone else seen this 2 line stamp? If so, on which models?

Thank you,
Dale

Dale,

Here's the 154OT produced for Hunting Magazine with the 2 line stamp and HUNTING shield

Well look who showed up. I hope you're well, Keith. Pick up any Camillus 72s or clones lately? Do you know why there wasn't a fall Badger show this year?
