Mighty fine !

Perhaps the earliest "crows beak" butt made? Not sure, but most definitely on a fighter. While WWII vintage, note the peened tang on a brass washer, only time I have seen that IIRC. Belonged to actor John Carroll, the original Zoro amongst many others including Flying Tigers with John Wayne.

Very nice.

Any info on that cool sheath?

Where's the blade?

That is fine. Let's see more pictures, please.

Mitchell has mentioned Cornish, but I don't know. I think all the Cornish sheaths I have seen were marked as such, but that doesn't mean it isn't a Cornish. Is sure looks like it could be, but perhaps that was the style for other makers as well. Hard to say.

My Dad's #1 which he got during Naval Aircorp training in Pensacola, FL in 1944. Not the original sheath, but it's been with the knife for as long as I remember. He tried to polish it with a dremel before giving it to me ~ 10 yrs ago (image2) and scuffed it up pretty bad, not realizing that it may detract from value. I have gently restored it by hand polishing most of the scratches out. I would like to get an accurate sheath someday. Thanks for looking!

Can we see a better picture of the sheath??

Here is the sheath. No branding on either front or back.
