Looking for a rare Schrade Sheath

[saskatchewan58]

I picked an anniversay North American Hunting Club lockback-gut hook stag handle knife. Also have the presentation box and original paperwork. I am missing the specific sheath for it. The sheath is a tan fold over type and the folding flap is stamped with an eagle clutching a rifle and bow? with the word SCHRADE in a semi-circle over the eagle. Apparently the stamp is the NAHC logo or medallion. I saw a pic of the sheath somewhere online but can't locate it now, so the description will have to do.

So here's the Question, anybody have a lead on where I can pick up this sheath? I've included a pic of the knife and materials.
