[78-L] What was the last label to denote electrical recording?

[Harold Aherne]

Here's one I've thought about a few times: what was the last label to contain
some reference to electrical recording? The Standard label (which seems to have
been recorded and pressed by Victor) still announced "Electrical Process
Phonograph Record" in the early 40s, and so did the Orthophonic make (used
for Greek and Turkish material and also made by Victor for Standard). Were there 
any others?
