I'm not sure if this will solve your problem, but I have an old jig saw that was my dad's. It's 1940's to 1950's vintage so like me it's probably over 70 years old. Anyway, as you can see from the photos, there is a hole at the top. In this case the hole provides access to a vertical screw that locks the blade in place. Have you figured out how to replace the blades in your saw? If not, shine a light down that hole, there just might be a screw that you need access to.
