I"m looking for a cheap source of storage boxes for O-gauge cars, anyone have a favorite place to get them? I'm thinking 3 x 4 x 14 would accommodate most of my requirements.
Try a sports card shop. They have a Monster box that may hold four. You need the boxes that store hard covers. They are about 3 by 4 and in different lengths.
I forgot about them till you asked the question. I also am thinking about more storage . I even have an antique trunk I'm customizing.
