Form the pictures it looks to be in solid shape. If so, shoot the crap out of it. These old bows have stood the test of time.
Once you get it strung up, pay attention to string allingment on both ends. Let it stay strung overnight before you try to pull it.
If all is OK, I would flex it a bit, then half draw, then three quarters. Once you can come to full draw with it, it should be OK. Pay attention to any wierd sounds while flexing and drawing.
The only concern that I would have is that if it has been sitting in the case since Korea, it may have gotten a bid dried out from no use. Take it slow and easy.
Others here may give different advice about dealing with old unused bows. Listen to them...they probably know better than me.
I have an old Tri-State Jaguar that has a similar design to riser.
