I can not see the firing position
But is it not possible to file the half cock?? for safety.
That type of lock presents its own problems. Probably never intended for set
triggers.I have made a lot of set triggers but prefer a good lock with a single
trigger like my Whitworth/Henry had.I had an original LH Goulcher that was
never on a rifle and the full cock position was a good safety and it had no
bearing thru the bridle either.
The only "Hawken"type I ever made was 50 years ago and it had the long bar
double lever triggers and a lock with two position tumbler and "fly" and I
made sure the lock could be cocked and fired with the front trigger only or
with the set trigger and the lock was able to be brought to half or full cock
without having to set the trigger.I think a lot of people trying to make a rifle
buy a lot of mismatched.semi useable parts and have no idea what a good
steel ruler of 6 or 12 inch length is used for.The results are predictable.
