Gibson K-2 model mandocello with a light to dark red sunburst finish, serial number 25254. The K-2 model mandola has a teardrop shaped body (like the A model mandolins). The mandocello has a carved, arched top and back, a design patented by Orville Gibson in 1898. Five businessmen bought the name and patent from Orville Gibson in 1902 and started The Gibson Mandolin-Guitar Manufacturing Co., Ltd. The oval soundhole has decorative binding of a ring of inlaid wood and a second ring of ivoroid. The binding around the top and back of the instrument, the fingerboard, and the headstock is also ivoroid. Mahogany is used for the neck, and the fingerboard is of ebony and extends over the soundhole. There are twenty-four nickel-silver frets with mother-of-pearl position dots on the fingerboard and upper edge of the neck. The floating bridge is a modern replacement (the original bridge survives in the case). The mandocello has the standard string disposition of eight steel strings in four courses, tuned in unison pairs to the pitches of a viola: C, G, D, A (one octave below the mandola). The nickel-silver tailpiece is engraved "The Gibson." The distinctive headstock echoes the scroll shape from the body has an inlaid "flower pot" design that was commonly used on high-end Gibson instruments, as well as inlay that reads "The Gibson." The Handel machine four-on-a-plate tuners are inlaid with a flower motif. The instrument has a raised pickguard mounted on metal brackets.
