Turkey call made out of a film case

[bucknduck]

Ok, here's a new one that I saw at the Birch Run expo show. I caught the tail end of one of the seminars and the person was using a turkey call that he used from a 35mm film case. This is the first that I've seen of this type of call. Did anyone else see this or make this type of call? Eventually I would like to try making a wingbone call.

It's a form of tube call.
Hard to master, but deadly when used right.
