[78-L] Wax (was: Film of Ann Stephens recording for HMV in 1945)

[Kristjan Saag]

Highlights the question: how long did record companies use wax instead 
of lacquer?
Lacquer discs were introduced in the 1930's in most countries; many 
radio stations used them for instant recordings. But what about record 
companies in the US, UK, Germany etc? Was it either-or or parallel 
techniques?
In Sweden wax was used by leading record companies well into the 1950's.

Do the esteemed members of 78-L think it looks more like wax or lacquer (or the compromise between the two, flowed wax)? The thickness suggest a cast wax blank, but the images aren't clear enough to be sure where the blank ends and the turntable/other apparatus begins.
