The thing that caught my eye when I saw the listing for that gun was the 0 in the barrel steel mark area on the barrel flat.

I didn't see a picture in the listing showing the rib markings.
From the earliest Quality VH guns I've recorded, the mark in the barrel steel location is K
f --

The barrels rib marked Titanic and Acme have a K in the barrel steel location near the front of the right barrel flat. I've recorded these K
f and K markings into the 134xxx serial number range. Beginning in the 135xxx serial number range I begin seeing the V, T, A in a circle markings.
Would love to see the barrel flats of some more of these 1895 vintage Quality DH guns with Vulcan Steel barrels.
