Hey Folks,
Wondering if anyone knows of a 209 primer conversion for the traditional sidelock/#11 percussion ML's?

A friend was asking me and I remember seeing something on the web some time back, but did not pay much attention to it then. The unit that I remember seeing had a 209 component that threaded in where the #11 nipple does and a gizmo that attached to the hammer-face of the sidelock to ignite the 209 primer.
