Rick, I found out who owns the bag and horn set.
Jeanne McDonald made the bag and horn strap.
Rich McDonald made the pouch and horn strap buckles.
Robert Weigert made the Berks Co. "bloodspot" screw-tip horn.
I found out who actually made everything a few days after I sent Lee Larkin a check to make the set.
I'll post some photos of it in a few months, unless something happens.
