I got this many years ago from JRCigars and it is no longer available. It is an authentic 1953 50 Caliber linked Ammo box that was converted to a Spanish Cedar lined humidor. I used this for many years as an aging Humidor. The seal can’t be beat and if your Cigars are balanced you don’t really even need to use the attached humidrol stone in my experience. The interior has a moveable partition and of course cigars can either be end up or one their sides depending on how many you want to get in and how many brands. Obviously the partition can be moved entirely as well.
I would estimate that end up you can get 100 cigars in there. Dimensions are 5″ wide by 10 1/2″ long and 6 3/4″ deep INSIDE the box and Cedar lining. I think that plastic on the top is original and cut to place the Humidrol stone. It could be removed if you want without effecting the lockdown seal.
