First Time Parker Owner

[Keavin Nelson]

Ian,
There aren't any "tests" that any US Smith would perform. However, there are a number of inspections and measurements that can be taken to verify bore diameter, minimium wall thickness of the barrels, and choke, chamber length. Of these, minimum wall thickness is the most important, and that measurement in concert with location on the barrel. There are quite a few members in RI and the surrounding area that can steer you in the direction of a smith to perform the measurements.
If the bores are in good shape without pitting, and it is tight on face, then it is likely solid to shoot with reasonable loads.

What Keavin said.

Parkers were well built and unless messed with, will keep shooting long after their caretakers are gone.
