Dr. Deer,
I'm happy to name the 'smith, he won't mind.
It's Jim Kent, Buffalo Gunsmithing in Toowoomba.
I won't put his phone number on here, but if anyone wants it, I'm happy to PM it to them.

The enlarged lever might be a bit harder on a BLR, from a trigger and manufacturing point of view I would expect.

Regards,
David.
