So the choke taper seems o.k.? Like I said, I've never measured this before but I expected the .035 final choke diameter to start further back from the muzzle.
Thanks everyone for your input, keep it coming.

Yep, math is wrong, but I'm Polish so it's OK.

Are you really? Yep I am Polish and I'm offended by Polish jokes as excuses for ........

I believe the issue of barrel honing can be overstated. Chances are if you have a typical "brown" gun that is in used but not abused condition, the barrels have not been touched. Plus, when you consider how Parker changed bore dimensions in the early '90s it can be confusing. That's where TPS comes in handy. This is, of course, giving no consideration to "high" condition guns of questionable provenance, which, in that case: Caveat emptor baby.

.735 would be the medium-high side of post 1895 12 gauge Parkers. It is way too small to be one of the earlier guns. Austin Hogan and I have both measured more than a few original appearing, apparently unmolested Parkers, especially single barrels, that are bigger than the nominal .729 or .730, some as big as the very high thirties. Remember, even if this gun had been honed from .729 to .735, wall thickness would only change by .003.

Also have a high condition sixteen DHE, also sent to Kirk, also with MWT .019" right ahead of the chokes, also, in Kirk's opinion and my opinion, left the Parker factory that way.

Best,

My CH is .018 and .022 right at the beginning of the choke. Bore diameter is spot on at .662 and unaltered. They struck them thin back then on occasion.

Not a damascus, but here's a Krupp barrel that's .018" wall at the start of the choke. Bulge became noticeable after about 200 rounds, 100 per barrel, of 1 ounce 6500 psi loads. The so-called gunsmith didn't follow what we agreed to on max diameter for honing. Bores are now .738" and choke diameter at the muzzles are .712 & .713". Not a lot of constriction.

I took the DHE 16 with the .019" pre-choke section to Argentina and put 3000 rounds of lord knows what through it. It has 32" barrels and weighs 7-4 and was ideal. No problem.

I don't think I ever shot the the DH Damascus gun.
