Hey GCR
On some of his hats he use a Hermann Heiser hatband, floral tooled, but not sure if it is a acorn and leaves tooling??
On some other he use a stetson made hatband, simple leather strap with rolled string slopped through.
I have seen one simple band, not sure if it is a leather band....
try to finde some more informations about the floral toold Heiser band in some of the old cataloges I have ... hang on, will get back.
So long
Andy
