Just finished my latest large custom cigar humidor build using a vintage US Military surplus wood crate that originally held
105mm rounds for M395 Howitzer cannons.
Lined with 1/4" solid Spanish Cedar, has two removable top trays, cherry stained, cedar Boveda pack holder and Xikar Digital hygrometer.
Purchased this box from a Army/Navy surplus (along with a few others) a couple of years ago and have been meaning to play with it. Finally got around to building one for a customer! Turned out great. Love the history of boxes like this.
