Thanks, J. It is a thoughtful configuration. Like a small top box from a stack, but portable.
I'm still trying to figure out when it was made. According to the catalogs, they added slides to this box in 1941. No slides on mine, yet green, not grey.
As for the restoration, I am going to replace the leather handle first. It's amazing how that changes the entire overall appearance of an old box. I am definitely going to preserve the original paint. There are some surface rusty areas I am going to apply some rags soaked in Metal Rescue for careful amounts of time, and three or four areas that will need grinding and sanding, I am afraid. Those I plan to touch up with some matching paint. And the entire removable tray needs paint, which is fine, because I have to braze the cracked handle. It looks like it probably had too much weight in it one too may times and lifted. But I am going to leave the other blemishes and wear spots. It will look better showing its age. And I will top that effort off with a reproduction oval sticker. Hopefully the eBay guy that Otg and d42jeep and others patronize will have one.
