The C is the mark of a Parker Bros. worker. The 4 above the D (indicating Damascus) in the case of your barrels - represents the 'level' of the Damascus. There was 2-iron crolle, 3-iron crolle, 4-iron crolle, 5-iron crolle and 6-iron crolle... yours is obviously 4-iron crolle Damascus.

The other 4 is for the pre-struck weight of the unfinished barrels - in the case of your barrels, 4 lbs., 3 oz.

What is the minimum wall thickness suggested in determining if I should proceed? I think I have plenty to work with, no dents or flat spots and mirrors inside the bores.

They may be fine but “mirror” bores on a gun that age with that much obvious use could be an indication of the bores having been honed and polished too much.

Different thicknesses at different places along the entire length of the tubes and as far around the circumference of the tube as possible should be measured.
