Older Linn Sondek LP12 info and interest

Hello all,

About 10 years I ended up with my fathers Linn Sondek LP12. I don't know much about it, and am seeking some insight. I've done quite a bit of research using Google image search and Wiki, and based on what I've found, this could be quite valuable but I really have no idea, and any insight is appreciated. I'd also like to get an idea if there is interest in this item from the community.

Here's what I believe I know.

• I think the turntable is dated between 1979 (spring loaded hinges added to lid) and 1984 (the year they changed to a clear lid). It's definitely pre 1993, as it has a pre-Cirkus subchassis.
• The internal circuit board, motor and some other parts have been removed and based on pictures it looks like the top of the line Origin Live Ultra Speed Controller Box, Motor, and Transformer upgrade was installed. (I have a bag with the original parts.)
• The tonearm is a Syrinx PU3 which looks to be rewired with most likely silver cable. The rewire doesn't have any names on it, but my father used Cardas for most things, so that could be it.

That's pretty much all I've pieced together. He was pretty obsessive about these things, so there may be other upgrades/mods installed that I'm unaware of or just don’t know enough to recognize.

Any observations or comments are welcome. I’m interested in knowing what this turntable might be worth, and what interest there may be.

Here are a bunch of pictures. https://photos.app.goo.gl/C3dgam97y9iU9c2E8

Thanks so much in advance!
