Up until fairly recently, I don't think a lot
of gunsmiths in the US understood how to refinish
an English gun.

ie type or method of bluing used, type of colour case
used on Rigby's, Holland's, Purdey's etc etc.

Just my HO.

And of course I have seen a few "doctored" guns in the US
to make them more valuable than they were - 375 rechambers
being one of them.
