The discography for the Gellin Kwintet and the Internasionale Oktet is incomplete in Alan Kelly's research on the history of the Gramophone Company. There is no information on discs from numbers 4320 to 4331 and 4360 to 4377. Below I have compiled the known tracks from Flat International, the Chris Albertyn Collection and Kelly's research:
Internasionale Oktet, c1930
A43687∆ Boslandlewe (Woodland Life - Waltz) (4331, 40-2331)
Gellin Kwintet, c1930
BE2144-2∆ Visserswals (Fisherman's Waltz) (Lind) (4331, 30-2432)
Gellin Borgstrom and Tognarelli, c1932
matrix Die Mooiste Meisie in die Wereld (The Fairest Girl in the World) (Waltz)
(Lindquist) (4372, 7-288418)
matrix In die Ou Dae (Olden Days) (Waltz) (Knutsen) (4372, 7-288426)
Gellin and Borgstrom's Quintet (refrain E. Hjordt), September 2, 1932
0PF3-1 Gellstrims polka (Thomsen) (4383, 30-10117)
The UK based Gramophone Company Limited (home to labels like His Master's Voice and Zonophone) was one of the first companies to issue South African music and had sent a recording engineer George Walter Dillnutt there with a mobile unit in March and April of 1912. The unit recorded material in Johannesburg and Cape Town that was subsequently issued on 78 rpm shellac discs and marketed in South Africa as the 4000 series on the company's Zonophone Twin label. The company would continue making recordings in the 1920s and 30s at its head office in London. The label pictured above shows the third design used in the 4000 series.
The last disc issued in Zonophone's 4000 series appears to be 4383 by the Gellin and Borgstrom's Quintet, probably in late 1933. It is likely that the above disc, 4331, featuring the Gellin Kwintet, was issued somewhere between May and December 1931.
I am indebted to Alan Kelly for his tireless research on the discography of the Gramophone Company.
