It's a good reminder of the sort of craft skills there used to be, in ordinary workshops.
If I could make one handle to fit one button chuck, with the brasswork neatly set in to the wood, I'd be so pleased with myself. I'd be posting photos on here, expecting compliments.
But the poor old chap who made yours didn't get that - he'd just have to start off on another, then another. He'd have been on piecework and I don't think he'd have got rich on the deal.
