Harvest Game Calls are from Mitchell Indiana. Charles Sorrells is the owner and call maker. I used to buy a lot of calls from them, but I am not sure if they are in business anymore. I will try to get a number for you to call. However, I have an extra custom glass over slate from Harvest unopened and new in hard plastic. They did our NWTF chapter calls in 2002. The call is glass over slate and has two strikers and diamond call conditioner. If interested email at [email protected] we ordered too many and would sell it at cost.
