Whilst sorting through some old kit I was given years back, checking out what was effectively beyond use and what just needed some TLC, I came across this unusual (to me) national hive with single-walled front and back, and double-walled sides.
A bit of research suggests that it’s a design that might go back as much as 100 years and was still in use in the 1970s, which I guess makes them quite possibly antiques 😀 I wonder if that means they’ll fetch more if I put them in the local BKA used equipment auction?
