The placement of the support, finger-holes and keys is awkward for the left hand. There is no tuning-slide but the crook insertion can be varied. L0: 3rd key (closed-standing). L1: 1st finger-hole, 1st key (closed-standing). L2: 2nd finger-hole. L3: 3rd finger-hole. R0: 2nd key (closed-standing). R1: 6th finger-hole., R2: 5th finger-hole. R3: 4th finger-hole. Keymount type: saddle (first, on brass); pillars (second and third, on wood)., Keyhead type: shallow cup. Repair History: The brass plate covering second three finger-holes may be an early repair. The drainage receptacle (boîte salive) is a simple modern replacement.
