Thanks for the info so far. More photos attached. The blade is only 7/8 inch at its widest, 3/16 stock. Handle length, including the spacer, is 3 13/16.
It doesn't have the blade width of the 11 3 1/4, and the stamp on the blade is straight not angled. Handle length and stated sheath don't match.
It has a drop point, unlike the GTR.
The grind differs from the Dave Griffin photos I can see online. His sheath maker seams to be the same as mine. My sheath has no "R", and has Fla. in the stamp. My blade is stamped with Fl.
I bought it from a gun dealer's table at a gun show in Phoenix. I am happy to entertain that it may be altered, or mismatched to the sheath. But, I have lots of other Randalls, purchased directly from RMK, and the fit and finish of this one appear just as finely done and original as any. It doesn't appear altered, and why would someone alter one?
Happy to show it to anyone more knowledgeable than me in the Phoenix area if interested.
