One of the old beekeeping boxes. The dates inside are from 25 years ago. The last beekeeper died 11 years ago.
They're rotten on the outside and full of mouse poop and god knows what else. Nothing much usable left there, I think.
I'll take them apart and recycle, mostly into sauna fuel and scrap metal.
Maybe keep the combs for melting into wax, will have to take a closer look later.
