Sears 244.210550 scope value?

[tpirsig]

I bought this automotive scope from Sears in 1982 or so, $500. It still works fine. I haven't used it in years, given that plug wires, distributors and so on are things of the past. Any idea the value of this? I'm trying to sell it, to free up shop space. The only one I could find on ebay, for comparison, was nonworking (parts only). I live in rural Hawaii, which complicates shipping (25 lbs and bulky). According to AI, the original manufacturer is Peerless Instruments, and this model is a precursor to the Sears 161.21056 automotive scope. Thanks for any feedback.

I had a Sun 504 that was great for setting up distributors, they still go for a few hundred clams... but the issue is finding someone who is into old cars that still run conventional ignition equipment. I think I sold it for $300 to a car collector who had a lot of 60's stuff... If someone has a need for it it's a godsend.

Or keep it for when you buy that '65 Corvair...
