Edison electric DD's in the 80 K series

[marcapra]

Why is there no information online or in books as to where the electric DD's start in the 80K and 82K series? I have a DD of Victor Herbert's The Fortune Teller Airs No. 1 and No. 2 on the L side performed by the New York Light Opera Co. The number is 80823. Is this record an electric? Thanks, Marc.
