Right. That sounds/looks right. Presumably the bark falls off with the passage of time. Rather pricey! But many thanks.

I'm not sure why it's pricey - it's cheap for the sawmill to make because it
includes the edge of the trunk, they don't have to trim and discard that
piece. Unless you're looking at say oak (when it'll be expensive anyway)?

Find a local sawmill who should be able to help.
For a randomly selected vendor, this is about 3 quid a meter for example:
