Have you gone to supply? I was told that supply was not issuing them anymore and only issuing crappy Bellvilles. When I threw my old boot clad foot onto the desk and said, “do you have any more of these?” The supply clerk said, yeah, we just thought no one wanted them anymore. The newest ones I have are made by Addison Shoe Company, the # on the inside of the boot is SP0100-050D-0380, Manufactured July 25, 2005.
