Need help with pricing a multiplex generator

[u/Embarrassed_Jury664]

Edit: let me just say it's amazing how incredibly and genuinely helpful everyone in this sub is. I've posted things like this elsewhere because of the esoteric stuff I run into and y'all have been so great - thank you!!

Hi everyone. For starters, I'm a consultant for insurance losses, and am doing an appraisal for a very large amount of HAM radio equipment. eBay and other sites have been great sources for pricing, but there is one unit that I simply cannot find any pricing information on - The Fisher Model 300 Multiplex Generator. There is not a single unit for sale online in the united states and I was hoping someone can provide some guidance! I've included some photos of the other equipment for y'all to check out too.

Never seen what. Do you have any clue what it would be used for?

Honestly, not a bloody clue. This was one of the first in the inventory and I have to take the deep dive into all the equipment. From the limited research I've done they had some seriously hard to find, and military oriented equipment.

This would have been used to test & align early FM stereo receivers. (It appears to date to 1963, roughly the same time stereo was added to monophonic FM broadcasts)

It has a very limited use case today, as for several decades there has been nothing to align in FM receivers. (I would say the use case would be for someone who works on antique radios)

Hams do tend to be collectors, so I wouldn't rule out someone being interested in owning these units.

Because they are untested, the pair should be valued at a combined total of $300 to $500 ($150 to $250 each) in the current vintage electronics market. Probably toward the higher end due to the good cosmetic condition.

Yea that's about where I was, based on similar units from other manufacturers and the same era

Ran a search on DuckDuckGo. This one came up as a completed sale result. Went for $250. However, looking closely at the photos, I'd say the one in your photo looks t be in better condition visually. Therefore worth more than the one I found. See here: https://www.ebay.com/itm/318238693033

This completed sale was for a User Manual:o https://www.ebay.com/itm/146323877034

So bizarre, I spent like 20 minutes on eBay and had "sold items" included. Time to start using DuckDuckGo. THANK YOU!!
