Who is old enough here to remember Lost John Turkey Calls. I would think that John T. Grayson has passed on to his reward by now. He made a interesting call that had a good sound to it. I miss those old time turkey hunter call makers. I do not know if they are still being made.
I had a Lost John Turkey call years ago. It was made by John S.... from Bruceton Mills WV. Sounds like a different callmaker.
There is a John Sisler who is or was part of the company. But I beleave that John Grayson is who came up with the call.
John Sisler bought the design from him. I used to know John, his daughter lived beside me for a few years. Nice folks. Last I heard, John was still making a few.
This is one of mine.
