What kind of leather? Cow, deer, goat, buffalo, or elk? There are quite a few suppliers out there depending upon what you need. I don't have them on this computer, but I can forward a few when I get back to the office. I'm sure many here have their own sources, too...prepare to be deluged. <g>
Cow, deer, buffalo or elk would be fine. Send whatever you have on. I'd be most appreciative and check them out. If anyone else knows of any place I can get a good pair of quality made officers gaunlets, send the name of the supplier along with any contact info. , I'll gladly check them out!
I would provide a bit 'o advice where gauntlets are concerned....they look pretty cool in a nice studio photograph, they are fine for blister prevention when you have a hard mouthed horse, but they don't work for shooting a pistol, tightening your girth, getting into your saddlebags and they're pretty hot in the summer. BUT....they are really good for pissing your pants...!
