I bought a SKS crate a couple years ago.
It was too stinky to have it in the house. Smell cosmoline and humidity.
I salvaged the metal parts from the crate and sent the wood to the junkyard.
I made another one out of cedar and pine wood with the same dimensions as the SKS crate.
Now it looks 100X better and it smells good too !
I don't think its asbestos but I wouldn't put that in my mouth !
