I think this one may have just what you're looking for:
This is from a pouch and horn set shown on the McPheeters Antique Militaria website:
Antique Pouch & HornWhile the dealer does not provide any solid provenance, it does appear to be a genuine antique. I don't know enough about these to speculate regarding its place of origin... I suppose it could be from almost anywhere in the US. I would have no difficulty accepting a mid-19th century timeframe for it, or possibly earlier.
If you will click that link, it will take you to a detailed description with a bunch of additional close-up photos, including at least a couple of the rolled leather button.
I have been wanting to make a copy of this pouch and horn set, and I think that could be pretty easily done after studying the photos and description.
Best regards,
Notchy Bob
