Gents I seen this for sale on E-bay I can not speak to authenticity but did find it very interesting as I have never seen anything quite like it before.
I thought I would post up the sellers description images and a link to the auction I guess we will see if it is a dud or warrants further discussion if not I apologize as it is not my area of collecting.
