How to Tune Goose Call--- PLEASE HELP

[FishN]

I have a Sean Mann "Eastern Shoreman" goose call that needs to be tuned. A friend thought it would be funny to take it apart and put it back together. It just doesn't sound right now. The black marks on the reed are index marks I made on it trying to tune it. They are from a Sharpe Pen. Any help would really be appreciated. I have attached photos of the call if that helps.

Thanks

Outside of just tinkering until it sounds right you may have to send it in. Most of the big name call makers will tune it for you for a small fee. I'll send a PM for contact for a guy who may be able to help you out.
