The Schact upright is still called the Matchless. I had the opportunity to spin on one last year. The son of one of my spinning students bought her a Matchless at an auction for about $100. Quite the price for just the wheel, but this also included every single whorl for the matchless and a tensioned kate.
I cleaned & oiled it up. I had a bit of a problem until I realized I had the bobbin on backwards.
I'm working on spinning my first cellouse fibers now. Hemp, flax and a 50/50 cotton/wool.
