Revisited this while doing some organizing. Obviously home made but unfortunately by whom...No idea. It is fairly well made , maybe made on a remote job site or work camp during spare time? Sockets are a mix of old Snap-on, Wards Western, Proto. Plumb & Herbrand. I had to look up Herbrand as I was not familiar, great reading, seems they were combined with Utica & Bonney under the Kelsey Hayes Co. Who knew?
Great old box and it has a history with you! I used to collect old tool boxes and paint some of them up to resemble old sign painter's kits. I still have quite a few kicking around. You might want to check out the Vintage Tool Box thread on here and also the Garage Journal forum.
