Re: Moldy smell in Old Railway Equipment Registers
No, they’re not cheap, but virtually all quality illustration board is now acid free, or buy “museum board” if you want to be sure, and make your own acid free box. You can glue it together, or just use packing tape ON THE OUTSIDE and you’ll have an acid free box much more cheaply.
Sounds like I have a couple of the remedies in the house already: activated charcoal for the fish tank filter and kittie litter. Acid free boxes don't come cheap . . . unfortunately.
