I'm just curious. (And if no-one here has a 1920 catalogue to refer to,
the price of any 5'9" Chickering Model A AMPICO from the 1920s will
suufice: though I've heard that there were 2 scales in this length. A
narrower one, and a wider one with a larger soundbard, and hollow
"resonating chamber" built into the bass side of the rim.

Thanks!
