Good morning, Richard,
My unfortunately mainly absent friend!
Yes, the both plain and selfconscious craftsmanship in forging these barrels is exactly what struck me too at first sight.
Their unusually crisp condition, with very little corrosion, immediately reminded me of that of the three Passau haquebut barrels in my collection, showing no rust at all:

Thank you for caring to respond,
