Throughout the years there have been enough toy guns gimmicked for the purpose of magic effects that one could build an entire collection based on this segment alone. This is a difficult to find piece of apparatus designed for the purpose of a visible vanish of a playing card a business card or a currency note.
This is well made as one would except from a piece done in this time period and made of metal even having oil holes as in those days things were meant to last. This is made for use with roll type paper caps with a flip up carriage which is activated by a lever just front of the finger guard.
The magician takes the item to be vanished and clips it at the front sight of the gun and once the trigger is pulled the cap sounds its bang and the item instantly and visibly vanishes! Condition very fine.
