Help with the age of snap on tool box sets

[rtoshelly]

Hello!
I am trying to do some research on a snap on tool box (3 tier unit) that belonged to my uncle. Ive looked on the bottom right back of all of the units and there isn't any markings. It does have the snap on metal plates however on the center front of each unit. It kind of looks like the chest from the 50's. If any one could give me some information possibly as to the year these are from and what it may be values at, that would be wonderful! I have a few pics to share, but it seems like it wont let me upload it, it says file is to big? Hmmm...is there another way I can get pics on here?
Thanks a bunch!

They are probably from the early 50s. They look to have been repainted. Not a lot of value, maybe 200-300.
