Welcome to the boards Raspootyn! Glad to have you here!
As everyone else has said, absolutely AMAZING find there. Very impressive! Thanks so much for sharing!
Is it possible to get any photos of the crates themselves? Maybe any external tags, waybills, or stencils that might shed some light on where these things originated before importation?
(I'd ask you about how they came into your possession, but I'm guessing you're keeping that close in hand (I know I would if I found such a treasure trove holding out for the possibility that lightning strikes twice!)
Again, welcome to the boards!
