Chopper,
BTW it is the standard of care for treatment of off face. English have been performing the procedure for 150 years.

I beg to differ that is the 'standard' for English guns. Do the English do this? Yes? Is it a good repair? Yes.
The standard? No.
Discuss re-jointing and English double with and English 'smith and he will invariably suggest a new hinge pin be made. Will the do other types of repairs? Yes. Do the generally prefer to? No.
Just my opinion and like a**holes, everyone has one.
On inexpensive guns (and even some expensive ones) shimming of one sort or the other is the way to go IMO. If you make a mistake or choose the wrong shim, replace it. Start cutting material out of the hook, no matter how good you are, and the chances of a major problem just increased dramatically.
