Just a few thoughts--I've never worked on anything of your vintage.

How's your compression? Seems that if you have a bunch of stuck valves your compression would be low, and the vacuum would be zero as well. Sitting in a museum for a long time might have caused a lot of things to seize up in unexpected ways.

But I'm only a hack amateur with a few decades of fiddling around with engines.

Also, if there are any rubber lines in this, you could see the lines suck shut on the "inside" while the outer shell looks fine. I've had lines (fuel lines from the tank to the pump) suck shut in a similar manner under vacuum.
