Vintage Craftsman tool box

[78C-10]

Hello everyone. I love old Craftsman tool boxes and scored this one on ebay. It is extra long with a tray that's in nice shape. It has a number on top that reads 6517. I'm curious as to the vintage of this box, is it 1950's, 60's?
Thank you in advance.

The crowntop logo is 60's to very early 70's (what that box is) and the heritage logo was about post war to the early 60's.

It's also a carpenter's box - the extra length is so it will hold a hand saw, in that ******** the underside of the lid.
