Boker salesman carrying briefcase

[Tanzarian]

Hello, I was wondering if anyone has seen one of these briefcase in the past or would be able to let me know a roughly estimate of its value. It seems like it's in good condition with only a couple of areas of wear on the outside.
Thank you all for your time!

The Cooper Tools tag means the case is from the late 1970's to mid 80's. Looks like it was made to display both folders and fixed blades. I suppose it would be worth $30 or more just for the utility use of it but a Boker USA collector would be the best market for it. Since it is not a common item it's very hard to come up with a value.
