A bit odd and perhaps difficult question but:
Looks like it says "24", so I assume it's c24 class, but I can't decipher the rest. Unfortunately, a better picture is not possible. The wood could theoretically be from the 60s-70s, but more likely around the turn of the millennium. Pressure-treated?
Anyone who either has excellent vision or has seen this variant of marking before?
Managed to slightly scratch myself on this cheese grater-style some time ago and occasionally get red spots on that area of my arm. Thinking if it's some old junk, so I have some background if I were to contact healthcare.
