Restauration of a guitar by Francois Roudhloff - Paris ca. 1835. Although all essential parts were original the instrument showed severe damages. On the treble-side a serious fracture had to be set. A 40 cm long rib crack was glued with a wooden ledge from outside. It had to be removed and was supported with cleats from inside.The repaired area had to be colormatched and varnished. The restored instrument is in the collection of Brigitte Zaczek and was used for a CD- recording in 2000.
