Old Made in England 7cm long Toy Match Firing Cannon

These came from a box at the back of the store of an old shop - so in excellent condition. 
7cm long, wheels go round, made of a soft metal probably lead, ENGLAND stamped along the side.
 The lever at the back moves in and out - to fire a matchstick - potentially lethal - do not give to small children or over enthusiastic adults...  

Instructions :The lever is on a spring - you pull it back, put the matchstick in the barrel (shorter ones are best) , release the lever, and, if you've got the action right , the matchstick flies across the room !
