Need help pricing these scopes

[twowolves80]

Hi! I know there's a bunch of gear heads on this site, and I've had luck pricing things here before, so I'm hoping you guys can come through for me again. EverettB has usually been my go-to, but even he is stumped.

I have a bunch of old scopes, including an ancient Sun Dynamometer, complete with the punch cards and all the parts, from at least the 60s if not older. I also have a Dumont engine scope type 901 that I can't find much on. The only one I've seen is on ebay and it's currently selling for something like $4300, but that seems a little optimistic... (http://www.ebay.com/itm/DuMont-EnginScope-Type-901-/161526193233?hash=item259bb61c51&item=161526193233&vxp=mtr) There's also three others, all in a Snap-On case.

If anyone can help me, I'd greatly appreciate it.

That is very old. I had one on rollers and the size of a giant toolbox. A shop gave it to me for free.

Nobody uses these anymore. There are plenty of handheld smaller ones to do all of your carbureted/points cars.

They are not worth anything. They take up lots of room for so little work.

Get you an alignment machine instead. Even the older ones are still very useful.
