Depth 26 3/8″ (67 cm)
Net Weight 600 pounds (273 kg)

Rim
Back Frame: Solid birch mortised foot-piece. Solid birch soundboard lining. Grand-type maple laminated closing rim; unequaled vertical strength and stability.

Braces
Posts: 5 full-length tapered solid spruce braces with a volume of 3,600 cu. in. (58,993cm3): assures that backframe will remain straight, promoting stable and consistent tuning. Strategically positioned with bottom ends tenoned into birch foot-piece for positive vertical alignment. Spruce fill-blocks between posts at top of backframe capped with solid birch backing board for positive horizontal alignment.

Ribs
Made from durable, resinous sugar pine to assure strong and constant support of string down-bearing on the soundboard. Rib ends are hand-fitted into their mounting surfaces virtually locking in the important soundboard crown.

Scale
Overstrung; twenty-six note bass/tenor break. Treble duplex. Tension: 37,500 lbs. (16,875 kg)

Plate
Sturdy gray iron; filled, CNC-milled, and sealed; bronzed and lacquered.

Tuning Pins
Premium blued steel with rust-resistant, nickeled heads.

Strings
Treble: Ten whole & one-half sizes from high-tensile Swedish steel. Bass: Swedish steel core wire wound with pure copper. Longest, pressure bar/bridge: 46 3/8″ (118 cm)

Hammers
Premium wool top felt over premium wool under felt; treated to resist insects and moisture. Compression-wired to retain permanent shape. Hard rock maple hammer moldings and shanks.

Dampers
Vertical-cut premium wool for effective dampening. Hornbeam heads for endurance.

Action
White, quarter-sawn hornbeam parts are bushed with specially treated wool action cloth for freedom from friction. Parts are anchored in hard maple rails. Dependable, Direct-Blow design permits ALL parts of the action to lie above the brass capstan screws.

Keys
European spruce, individually weighed-off. Chip-proof, stain-resistant coverings for naturals; slip-proof, delicately abraded ebonized sharps. Tough, durable Linden wood buttons reinforce keys over balance rail permitting maximum tonal power with every strike. Longest: 16 1/8″ (40.9 cm)

Keybed
Made from planks of stable, quarter-sawn poplar. Horizontal planks are freely mortised together, while their ends are permanently mortised into vertical planks made of birch, presenting a vented system for humidity escapement while allowing for necessary expansion and contraction. Hand-milled to be flat and true correlating with keyframe for snug fit. Strong, rugged construction provides a solid mount for keyframe and action allowing for precise and prolonged action regulation. Thickness: 1 3/4″ (4.45 cm)

Pedals
Heavy, solid brass. Soft, sustaining, and full sostenuto.
