Would like to help but I must confess I've never heard of it.

I did a google search and found this: http://www.mackspw.com/item.asp?im=KOL823&d=Lohman_Mini_Pump_Action_Y elper_Turkey_Call

For 6 bucks I would just buy another one. I pay more than that for diaphram calls that only last me a season.

Good luck.
