Hey there, nice looking group of tools. Do any of them have any markings on them... makers names, numbers, ect.? That would probably help us figure out when and where they came from. Do the tools that have "screw mechanisms" on them work correctly--- are the teeth in order? I'm not the best person to ask about this. But, you have pictures posted---- which is GREAT!!!
So, let us know if you can find any "markings" on the tools. Particular the wrench, it should have a marking on top of the jaw, on the side, or a number on it. But, I'll leave that all to the experts.
Looks like a good find,
cheers, bird
