these next three photos are of the same barrel piece,my longest one.the first is mid gun just down from the trunnions its 2 in thick

this is the beginning of the end of the barrel (this is also the thinnest the iron gets on the gun)it’s an inch and5/8

this is one notch up on what I guess would be the flare it’s an inch and 1/2

this is the last step up the flare at the end of the barrel it’s an inch and3/4

this shows how it steps up in thickness at the end it seems fairly precise.
A few other notes of curiosity

maybe black then painted white?

this is the piece of barrel that was straight down in the ground


see how the sand seems fused to it all my other pieces cleaned right off this sand is on there.

and lastly for tonight a peak down the barrel.
I’m working out of cell reception tomorrow any questions I’ll try to respond after work.
AARC , I know I haven’t reassembled yet it’s time consuming and I really want to get it right.
