I’m digging through lots at a invite site looking for equivalent pieces and their parts.
What I know off hand is they are expensive or worthless.
Right off the bat. Paper!
Manuals!
Cash for nothing.
Ebay works but two better choices for price if you don’t mind waiting around.
If you can get through the nonsense of doing so get an Amazon seller account and post such manuals in the industrial and scientific category. Under medical.
The number one source for printed tech manuals is Amazon search engine wise.
Also
https://www.alibris.com/sellersThey’re surprisingly indexed under all sorts of speciality search apps.
I sell and buy VHS tapes here. They’re a much more, er, elite, clientele over all.
The 5810 ct has a used working (complete) rate of about $3000-$7000.
But looks to go well as parts. Hundreds for individual working pieces.
Even a case sold for $250
The nicolet 760… a few hundred to around $1000 mint.
So some lesser parts value there. I need further time to dig on it.
The pike will probably get you a low end of a few hundred.
But I found sales on that manual for over $100. Most in the $50-$60 range.
Alibris isn’t free. And the more you spend the better your reach. They are ONLY a media site and generally targeted towards books. Books with an ISBN or DOI.
But I sell comics and manuals on occasion. Both system and game manuals.
Magazines as well.
The numbers above are just passing ranges.
With an ebay store account you can access something completion rates for a paid upgrade. This shows not just “sales” where someone finished the high. Odder or bin buyer. But the actual money transferred.
Supplies things to be found. Like yes!, people really have paid thousands for Disney Diamond VHS! (Wtf, why!??)
Yes that rc car with the custom butane tank engine did sell for $1450.
Etc.
On industrial equipment you’ll find a lot of “sales” lack completion. Meaning the money didn’t pass through ebay or PayPal. If at all. That’s a lesser concern now with eBay Managed Payments but it tells you to take “sold” prices with the air quotes around them.
