I have been restoring Snap On boxes for a number of years and I am usually able to date / ID boxes by perusing my catalog collection and the ones available here.
However, this one has me stumped!!
I am reasonably certain it is pre-war, and likely 1920-1930's vintage, but I can not find an exact match in any of the catalogs. Take not of the two pull out top trays.
Most of the stuff I have restored is post 1950, so I am in new territory here with even 1940's vintage...
I presumed pre-1940 due to the leather handle, but I have no research or experience to back that up .....my guess of pre-war was just my preconceived notion!
Thanks for setting me straight.... I honestly do not know what time period they used the triangle logo in.
I am still stumped having re-perused through the 1940's catalogs...
I even considered the drop in trays were added at some point, but they are too well constructed to be homemade and the paint / patina matches the rest of the box very well..
So, I am currently inclined to think they are original.
I also considered this might be a 3/4 drive box, but the dimensions are wrong.
The exterior of the box measures 18.5 L x 4.5 H x 6 5/8 D.
