There's a Ruth Etting short, circa 1935 that has a great opening showing an
ET sized master being cut in a control room. It transitions to her singing
in the studio and thereafter to the story that the film portrays I think
that the disk is wax but haven't seen it for X years. Perhaps it is a
lacquer. Search amongst her shorts & you might get lucky ( (double entendre
intentional). If you do find it, then I'd appreciate knowing the title and
from where a copy might be obtained.
There's also a delightful promotional short depicting the production of a
Command Performance. It includes Bob Hope, Judy Garland and Lana Turner.
It's seen it several times on TCM. I think that it includes a montage of
the recording and distribution process. The montage might contain a shot of
a 16 or 17" lacquer being cut, because that's how the AFRS was mastering
their programs during WWII.
Another possibility is to inquire at the Pavek Museum. Their technical
collection is stupendous. I wouldn't be surprised if they have an operating
lathe. BTW I have about ten never-cut 16" Audio brand lacquers & would
contribute one if newly produced footage had to be shot.
Yet another source for cutting ET sized wax is the 4 reel Vitaphone Film
made in Sept / Oct '26. It has shots of recording, shooting and playing
back such films. The host is Edward B. Craft, then a Bell Labs VP.
Problem: I can't dredge out the film's title from my memory cells as I'm
