I'm in the process of cataloguing town anniversary medals, tokens, badges and fobs issued by all US towns (for their centennials, sesquicentennials, etc.). Wendell's (formerly Wendell-Northwestern), Minneapolis, was by far the largest medalist during the 1950's-1970's (or longer).

Does anyone know if their records pertaining to medals and tokens they struck were preserved anywhere? I'm looking for all details, e.g., mintages, descriptions of the obverse and reverse, diameters, types of metal(s) struck, issue prices, pictures, you name it. BTW, I called the company several years ago and they told me they do not retain records and none were available for research, etc.
