The Mark 2 Trigger Modification
The modification that defined the Mark 2 rifle was the
moving of the trigger pivot point and anchor from the triggerguard to the
receiver. Pictured below are examples of the Mk2 trigger assembly with
comparison pictures of a No4 MkI. Followed by images of the fore-end
modification that was necessary to accommodate the new trigger mounting.

The trigger is pinned to the receiver group from a
boss located on the buttsocket. Note the U shaped cut just above the trigger
pin. This notch is to allow room for the fore-end reinforcing tie screw, which
became necessary after the trigger, was moved and fitted to the receiver.
Before this a metal band was used to reinforce the stock but because of the
added boss the fore-end had to be altered. For this reason, fore-ends are not interchangeable
between the MkI and Mk2 rifles.

This image shows the removal of the wood from the back
of the fore-end to allow it to fit around the new trigger mounting assembly. To
replace the metal re-enforcing band that was used on the MkI models a screw was
added to secure the rear of the stock.

Seen here is how the fore-end was contoured to fit the
new trigger assembly.
