Question on model cannon
« on: July 06, 2011, 10:54:13 AM »
This cannon is from a long past auction; does anyone have any suggestions as to how that "apparatus" on top of the breech operates to fire the piece?

Cannoneer,
Maybe one piece is a horizontal, spring loaded plunger that is pulled back till it locks in place.  The lever on top is pulled with a lanyard to the rear and releases the plunger.  The flat surface on the front of the plunger strikes something that is missing and should be mounted where the four screws are.  It looks like the vent hole could be between the two front screws.
I just made all that up. ;D
Its possible.

A part is missing that sits on top of the vent, looks like it broke off or something.  The cylindrical thing to the right of the vent in 2nd pic has a horizontally-acting striker, cocked by pulling to right.  The sear shaft is vertical and is pulled up by the lever with brass handle, when brass handle is pushed downward..  That releases the strriker which then impacts some kind of cap or primer in the missing piece.  The missing piece communicates the flame to the vent.  Bang!

Thanks. I agree with all of your opinions, the metal piece attached over the vent by four screws evidently had a top part broken off, and there must have been a nipple facing the striker where the cap was originally placed.
I wish I'd seen this auction when it was active, because in 2007 this gun sold for 115 bucks.
