Anyone ever see a USGI Boyt Saddle Scabbard built for an 03A4?

It was on Ebay, and the former owner billed it as a GI piece, and said a real M1903A4 fits in it like a glove. It really looks GI, original configuration started as a WWII Boyt M1903 piece, with the added scope cover both riveted with six GI style copper rivets and closely machine stitched on. Aging and verdigris makes it look like it has been this way for a long time. It is black, but much WWII leather got turned to black in the 1950's.

I'm looking for help in locating a USGI document that would reference it - it is not unreasonable that the Quartermaster Corps would order such a scabbard, with 20,000 03A4s ordered and used in both Europe and the Pacific, and mounting M1s, 03s, Thompsons and BARs on Jeeps and other vehicles was regularly done with GI scabbards and visible in period photos. Any info, photos, etc, would be appreciated. CC
