That's nice. #1 calls are special and hard to come by! 
Jeff, You know that is an understatment in more ways than one. I know you are kidding and your #1 will roll off this ancient and worn out press soon. I stare at part of your #1 every time I go into my shop. It is a coming my friend.
You think about all the callmakers out there, past and present and what has already been done. To come up with a novel idea, that kills turkeys or helps in the process, is a Miracle.
Double Gobble is a miracle. Why it has never been done before, I believe, boils down to one fact. Most callmakers try to put every kind of call that has ever been made into one box. CAN'T BE DONE. I have been making calls for 26 years and hunting turkeys for about 46 (did not start till college days). I tend to believe in giving them a box that they like. What you find is there are certain birds that will be turned on by one particular turkey sound that will move his feet. It may be a hen or a gobbler sound. My hunting partner, of as long as I have been hunting, would say, "make me a box that does this, or make me a box that will do that." He has been hunting them since childhood, and now has about 15 different boxes of mine. All that will "Do This". One opening morning, he came down from the lodge where we hunt in South Ms. He was having trouble negotitating the narrow stairs from the upstairs bedrooms. I told him, "You look like Santa Clause". He said "That's because I have 5 of your boxes in this hunting coat."
This new box will serve a purpose both Spring and Fall, but you will need another one to compliment it.
Jeff, Before it all said and done, you my friend, will have enough Mr. E boxes to look like Santa Clause. You can bank on that.
Mr. E
