The left barrel has an H and a set of numbers near the forend lump. They same number is spread between the extractors, on their backsides.
The section of bottom rib between the flats has a number 5, set part from the serial number, which matches the rest of the gun. I would post pictures, but havent picked a replacement service for hosting them.
The bores are really nice, which is usually not what I end up with. The dents are being assessed and raised on Friday.
Not being in the position to collect at this time, if this configuration is of importance to someone, Im happy to let someone else have it. At least its not laying around in a pawn shop anymore.
