Help with DH bore diameter please

[redoftx]

Well, the chambers are original 2 5/8", the min. bwt is .045, and the bores are .754 right bbl and .755 left bbl. Chokes appear to be .033 in both barrels. The serial for the wood under the trigger guard matches the gun and grade (3). 1 7/8 dac, 3 dah, and 14 1/8 lop. The shotgun weighs 7lbs 7oz. I couldn't tell in the auction pictures, but the continuation of the "line" from the bbl flats, across the forend iron and to the forend wood under the barrels is visible. I was hoping it had not been sanded down or off completely. I do think someone has put some varnish or clear shellac on it. I'd be really surprised if the wood condition is original. Checkering is still strong. I will now send off for the letter to see if "DHH" ordered it, or if the letters were engraved by a subsequent owner. I'll report back when the letter arrives. Thanks to all who posted.
