If you are looking to purchase archery club patches you might try contacting the Wisconsin Bowhunting Heritage Foundation. These are the fellows who created the WI bowhunting museum at the WBH headquarters in Clintonville. The WBHF does have an extensive WI club patch collection and they may have extras available for either sale or trade. Call the WBH office at (715) 823-4670 to get contact info for the WBHF.
In addition, the American Broadhead Collector's Club was started in Madison in 1974. (PS - it is now an international organization.) They do have club patches but I do not know if they are available to non-club members. You could try contacting Larry Whiffen Jr. in TN at (931) 287-5566. He is an officer in the club and might be able to advise you on how to get a patch.
Also, you might try contacting Randy Hinkes at (262) 392-3454. Randy lives in Mukwonago and is an avid collector of archery & bowhunting memorabilia. He may be able to help you through trading or selling. (He is also a director of the WBHF.)
Good luck in your pursuit. I understand the collecting passion. I chased broadheads for decades!
