Guitar for sale
1920's Cathedranola
22 fret-23" scale Tenor/Plectrum

A rare instrument, possibly "one off" made by an obscure builder.
Usually seen as a Tenor Guitar in the same configuration as the guitar in the ad above.
This one is the 2 point body as shown on the mandolin exaple
See this link below for an example of the standard body guitar.
These are not true "resonator guitars"
They are wooden top instruments with a faux resonator cover.
Other makes also did this as an option.
Here it is called a "Tone Amplifier"  
So this is really, at 23' scale and 22 frets, a Plectrum/Tenor Guitar
22 fret extended fingerboard
23" scale

Tuned CGDA
Can be tuned in plectrum, GDAE, DGBE, etc.

Made for the Slingerland Drum Co. who also made some very fine banjos and, who also marketed  mail order instruments under the name "Liberty"
It has a nice warm tone as a 4 string guitar would with a metallic resonance from thecover plate.
The original finish is thin, as will be the replacement Lacquer. 4 coats
Frets are original thin wire, freshly dressed
Peghead, neck and body stripped, and 3 fresh coats of nitro lacquer applied.

Side markers added.
Grover 2:1 geared tuners and ivoroid buttons.

Highly figured maple neck
Body is 2 point, and very well made
Neck angle is VG, as is action.
Grover  bridge.

Strings touch cover plate for resonance and it sounds like a resonator guitar.

 Thanks for looking and sharing.
