See also Canada patent 6,821. The Mole Tire Shrinker was very popular and was available through the Sears and Montgomery Ward catalogs until at least 1919. The three manufacturers listed are just the three that we know of; there are likely quite a few more. More research is need to determine who used the patent while it was still in force. |
