Almost have enough saved up to replace the wheels on my half scale Napoleon. Will be buying 30" wheels that are designed for use on a firing cannon. Have the choice narrowed down to either Hansen Wheel and Wagon Shop or The Spotted Mule... both have links on the "where to find" references page. The price is pretty much the same from either. Just wondering if any of you have any experience with either company? What do you think of their wheels? Any input would really be appreciated.
