Hello, MMD.  Since yesterday I have found a screw that secures the
Temponamic knob to its shaft so that problem has gone away.  However,
on reading my posting in MMD 141125, I realized that I had got so
carried away in describing my troubles that I hadn't asked the vital
question: does anybody know what is the thread specification of the
screw that secures the very long tempo indicating lever to the middle
of the Temponamic lever (in my upright Steck D-A)?  Sometimes I
wonder about myself.
