Metal lining was commonplace on what are now antique humidors. They are fine to use for your cigars and if they have a lip/edge seal that isn't damaged, they tend to hold humidity very well. Think of it like a tupper-dor that actually seals well, or better yet, an ammo can-idor.
Cedar smell is likely from boxes being stored in there.
Does it come with a ceramic humidifier?
