And,
they've been claimed.
 That was fast. 
 Yes, I can imagine. I gave mine away, and now I'm missing it ;-) 
 
    I did too, with both an 11/750 and an RK07.  The RK07 was never
 used on the 11/750, though.  I regretted it for years.  A few years
 ago, though, John Wilson gave me a pair of RK07s (one of which
 runs!), and last fall, I picked up an 11/750 from Patrick. 
 
 Oddly enough, I'm giving up the 11/750 (the third or fourth that has
 gone through my hands), mostly because it's too small, and not nearly
 as interesting as my 11/780(s). :)
