This XV century rought iron falconet chamber has already been shown here.
It is presently laying on the lower shelf of my TV set stand, so i watch it a good couple hours per day.
As time went on, i wouldn't cease thinking abut its 'naked' situation, standing by its own on a little two forked base.
So i thought i would replicate the breech section of a falconet, in a stylized manner ... made of mahogany wood.
You may find this an awkward solution, but it brings some cosiness to the lonely chamber, anyway

.
Having failed the calculations to allow for reasonable space in the back of the breech, to lodge the chamber flat wedge, i decided to minimize the problem by using a cilindrical device instread ... the front section of an old muzzle loading firearm ramrod
