20461-R M22-0 3-Point Prototype

20461-R M22 3-Point Prototype

Beautiful blackface 3-Point prototype mandolin, red spruce top. This is the prototype, signed February 2004, 61st instrument Hans built.

Edited description from Acoustic Music Company’s online advert: “This is a varnish early florentine 3-point style Model 22 made with Bosnian maple and topped with Adirondack spruce. The instrument is a blackface,  Schaller tuners with ivoroid knobs, 1 and 1/8″ bone nut, fine sculpted ebony pick guard, scooped extension, flat fretboard, masterful fit and finish. Custom Calton case to accommodate the elongated 3 point body. This mandolin was the prototype (and is designated as such on the label) for this model.

From Mr. Brentrup:  “The 3 point mandolin was Orville’s original (circa 1908)  florentine instrument and is a very difficult build. It has a very different sound which is well suited to old time string band music.””

90481-R 2004 M22C Classic Red Spruce (3-Point)

2004 M22C

90481-R Signed September 2004, 81st instrument that Hans built.

Classic (3-Point), second prototype, red finished red spruce top, rock maple back, and normal 5 degree neck angle, transverse brace, 14 fret to the body (The advantage of the 14 fret neck is more manuverability around the neck, and by moving both the bridge and soundhole forward, some tubbiness may be taken out of the tone. This is a larger bodied instrument than the modern F-5…some 3/4″ longer and 1/2″ wider, so the instrument has a deeper, more resonant sound to it.).
