Help with DH bore diameter please

[redoftx]

Sirs, tomorrow I will have in possession this Parker DH.

I was wondering if someone who has a Parker close to the year of mfg. of this one, could measure their bores and tell me what they should be. Nominal 12ga is .729, but could earlier Parker 12's have been bored a little larger than .729 to accommodate for brass shells and BP? I have a verbal inspection period so that I may determine bore diameter and BWT is acceptable.

Also, if it's a keeper a letter will be forthcoming. I wonder who "DHH" was and is this Parker letters on the oval shield or your local jeweler?

thanks, Robert D.
