Doug,
Nice set of knives..."BUT"...(There's that word again)...the leather knife is not one of my Stanaback Specials. It is not seen often, that much is for sure, but it is a Model #8, Trout-N-Bird, in leather. Stanaback Specials have a "BCP" (Bowie Clip Point).
Hope this helps, Capt. Chris
PS: Here's the only quick pics I have of a 4" leather...and the stock is 1/4", verses 3/16" on a Model #8-4"...CCS
