Shall I take photos of the pretty boats at the Black Country Museum? No, I'll concentrate on the rusty steel hull.
I'd assumed this is a lighter, or perhaps "butty" boat that would work with a powered narrowboat through the canal system but James Finister tells me it's a day boat and I'm not going to argue. At the very least there is something to learn about the construction of these vessels, and how the steel plate weathers.
You can also see how much can be seen of the sunken boat next to it - another handy modelling hint.
