Tom: Thanks! I always enjoy posting to folks who are interested in my drivel. :-)

Joe:

1. Maybe you misunderstood me: The post war Model 3 sheaths are large throat. From my experience the (small) pre-WWII / (large) post-WWII sheath throat width has been 100% consistent with the only exception being Tune's sheath.
2. There were some "3 1/2" Hunters both before and after the war. (For those not familiar: Pete Hamilton coined the phrase "3 1/2" meaning a Model 3 whose spine was uplifted at the end, but not as exaggerated as A Model 4 skinner).
3. Yes / thanks: My Dad's knife is mid '46.

Tune: My pleasure. Ack'd on the Ni/Ag pin. I've seen a lot of Model 3 sheaths, and IMO yours is one of them for sure. The tell is the curvature.

JE: My pleasure, Sir.

Best,

Ron
