Roller Locks

I have the privilege to know Bob Roller and would like to show five of his locks.

From top to bottom and left to right

Twigg

Durs Egg, Durs Egg

Manton, small Ketland

The big Twigg is 5 11/16 long and 1 inch wide, the Durs Egg is 5 and 1/8 long and 15/16 wide, the Manton is 4 and 11/16 long and 7/8 wide, the small Ketland is the same as the Manton.

The Ketland has no frizzen Roller, but has the attractive early style hammer.

Manton up close

There is a roller on the frizzen and a cam hump on the spring   

The Twigg up close

And the Twigg cocked

And the Ketland half-cocked and cocked. That is precision lock geometry, big and small
