No other marks than what I said, didn't get to weigh it.
I mentioned the wall thickness in my other thread about wall thickness, it's about this gun.
I have to say I was only able to estimate wall thickness by measuring the barrel's OD and subrtracting the ID, then x.5.
The breech walls were very thick, the gun was actually listed at the auction house as a 10ga.
I came away with still plenty of thickness. Was not allowed to pull the locks.
At the time this gun was built 12C was good for up to 3", anything longer was marked 12L.
