I was pleased to see the thread on the Link trainer in the Monday
MMDigest.  Back in the 1970s I had begun my collection of mechanical
music machines and was familiar with Link and his trainer.  One came
up at an auction in West Liberty, Ohio, and I was lucky to purchase
it for $350.

As stated in the MMD article, in addition to the airplane unit there
was a large, extremely heavy desk that actually was a platform for
the movement of the "crab" -- a navigational training device.  The two
units were so large they had to be placed in my semi-truck garage.

After a few days of operation, it became clear that I had bought
another amusing but totally impractical object.  The Link trainer was
eventually sold to a gentleman who took it to the Phillipsburg, Ohio,
airport where it may still be if anyone is interested in filling up
his garage.
