I have been lurking around these forums for a long time, and have always found the information i need here, but I cannot find a single bit of information regarding these ammo crates i recently picked up. So, i decided to finally make an account and ask for some help. The ammo crates i found are marked as 20mm inert primer. I found a stamp with a date on the inside of one of the crates that says, "LEIRD LBR CO. L.&B. LITTLEROCK. ARK. SEPTEMBER 1944". I have searched all over the internet, but cannot for the life of me find any information on these. I will attach a link to an album of the ammo crates and other stuff i managed to get. If anyone can point me in the right direction, I would sure appreciate it. I'm running out of shed space and need to know if these are worth hanging on to or not.
