Kersten Lock

Kersten lock - A crossbolt running laterally, just behind the breech face, through the top of the standing breech of a break-open gun which passes through a complimentary hole in a flange extending rearward from the top side of a barrel. Named for the inventor Gustave Kersten. Similar in operation to a Greener crossbolt, but for more practical configuration, oriented towards the side of the bore; and therefore more suitable to a single shot or over/under gun than a Greener crossbolt would be..

Also, below:   Double Kersten Locks - Two such locks; one on either side of the barrel set. A system of lockup usually found on German over & under shotguns such as Merkel and Simson.

Locks - closed.

 Locks - open.   Below, with barrels removed.
