Nice box with lot of original paint. I would clean it with warm water and soap.
Thanks for the ID- I was thinking that by the date (1936) that it may be a WW2 box-not bad for a $5 pick up.
That is a very cool find, than I read how much (little) you paid. Good Job on this find, keep up the good work. What are you going to do with it?
