Correctly: Seeburg Model L ("Lilliputian") keyboardless coin piano.

There's no such thing as a 1917 Seeburg Model L, as the Seeburg Piano
Co. didn't introduce the keyboardless style L until about 1921.  I don't
know of a fully-restored L that has changed hands in recent years, but
unrestored examples in good condition have been selling in the
neighborhood of $3,500.  Add to that the cost of a complete restoration
for a ballpark restored value.
