Down-striking discovery (non-technical)

[Clark]

My post about Robert Wornum activated my down-striking receptors today;
I already knew that drop-action spinets (in this case, WurliTzer) would
play upside-down, but today I discovered that with stronger
hammer-springs and a spring on the rest-rail they will play and even
repeat on their backs. The progeny of the inventor of the cut-down
upright could reposition keybeds and sell left-handed, square 36" grands
with the bass in the right hand...
