We'd love to hear you say that you plan to clean it up and play it. with step by step details. and lots of pix.
Value. Good question. Flipperless pins aren't a real high-demand item, except among the relatively few folks who are into such things. Then again, if you could get a few folks who just had to have Williams Model #1 to fight over it - who knows?
Light bulbs and rubber rings are readily available, coils should be too. Bumper skirts will require some ingenuity if they need replacing. There isn't much else to go bad.
Suspense was indeed the first game made by Williams that was not converted from an earlier game. There isn't much other history out there.
It did get a mention in this conversation between Harry Williams and Russ Jensen.

btw.... ipdb could use some better pix of SUSPENSE if you could manage it.
