The best source for Tel-Electric information is Volume 6 of our
Billings Rollography.  It is available from AMICA (Automatic Musical
Instrument Collectors Association).  It contains over 600 pages of
historic and technical data, plus alphabetic and numeric lists of
roll titles.

Up to 10,000 Tel-Electric 65-note and Telektra 88-note systems may
have been produced from 1905 to 1917, when player production ended.
There were probably no more than a few hundred Telektra systems
produced, and an unknown number of the paper roll versions.  The
company went out of the player business in 1917 to produce material
for the war effort.  It never made players again.

Perhaps 10,000 roll titles were issued, of which we know about 6,000.
Most were arranged, though in 1912 they began issuing hand-played
rolls.

There are probably a dozen or so operating Telectric and Telektra
systems in the U.S., plus an unknown number of unrestored systems.
We know of only one system outside of the U.S., in England.
