Tom–These types of cabinets might seem like great cartridge storage, but in reality they are bad for such use. Back in the 1940’s & 1950’s many people were using Typesetters and Thread Spool cabinets, and people noticed that all their lead bullets were turning to white powder. The problem was traced to tannins from the oak wood normally used in these cabinets.
A better choice, and usually less expensive, are used metal Blueprint or Map files. You can often find these for $50 or less for 5 drawer units because everyone that used to use these big files have converted to digital
copies stored on computer.
