Flute. Nominal pitch: C.

Technical description: Cocus head; ebonite body and foot; 3 sections; silver keys; 4 silver ferrules; oval embouchure-hole; large finger-holes; no tuning-slide; screw-stopper; metal-lined sockets and tenons; cork-lapped tenons; short lower tenon; modern-style foot mechanism arrangement. Of the full, final Rockstro system (1877) this flute lacks: (i) Lever by which upper C? hole may be partially closed by L2, and (ii) Small vent-hole connected with upper C? - but see repair history below. Otherwise this is the 1877 Rockstro system, and has the 1877 addition of a large hole connected to the D trill. It cannot therefore be classed as an earlier model. The 1873 addition of a lever for L1 to produce B? with L0 removed is on this instrument operated by R1. The 'Rockstro Model' was manufactured by Rudall Carte & Co well into the 20th century (Rockstro 1890, paragraph 681; Toff 1979, p.112). L0: PL - B; Br B?. L1: PL - C. L2: A. L3: G?. L4: G. R1: F; D? trill; dup B ; B? trill. R2: E; D trill (opening upper D hole and large dup upper C? hole). R3: D; Rockstro F?. R4: D?; low C?; low C roller. Keymount type: rod/pillar; needle springs except for L0 keys (leaf). Keyhead type: cylinder cup; covers for finger-holes were originally perforated (the pads still are) but have been filled; pads for non-perforated cups have central screws. Repair History: A hole appears to have been filled above the upper C? hole. This may originally have been a vent hole.Technical description: Cocus head; ebonite body and foot; 3 sections; silver keys; 4 silver ferrules; oval embouchure-hole; large finger-holes; no tuning-slide; screw-stopper; metal-lined sockets and tenons; cork-lapped tenons; short lower tenon; modern-style foot mechanism arrangement.
