This trigger guard is from a Winchester 52D International. It apparently has a hard life. Wanting to keep the trigger guard as original as possible, I had to make a tap which has a 12×36 pitch. Once the tap was made, I had to make an escutcheon. The outside of the escutcheon, I used a 3/8×24 thread. Then drilled and tapped the trigger guard for same. Also, placed two pins down the sides of the escutcheon so it wouldn’t come undone. A skill I picked up from building Triumph motorcycles.
