I don't usually respond to telephone calls offering player piano
rolls for sale; I have more than I know what to do with, stored in two
locations.  When the phone rang today with an offer of rolls I told
the caller I was not interested.  Besides, they were 65-note pin-end
rolls as she described them to me.

After much begging to "take them off her hands" I went to see them.
Boxes upon boxes of rolls greeted me and I did not give them more than
a casual glance.  As I hefted one box off of another, I noticed that
the rolls underneath were just a bit different than the rest.  The
boxes were larger and the labels said "Electrova".

I ended up buying the box of Electrova rolls.  When I got them home
and began to examine them, I noticed that I really had three different
types of rolls, all spooled five tunes to one pin-end spool.  The most
unusual were the ones with the "D" shaped perforations.  I thought
immediately of the early Encore Banjo rolls.

Anyway, I can find out little about these rolls.  The two reference
works I use, "Treasures of Mechanical Music" and "Encyclopedia of
Automatic Musical Instruments", offered little help.  You will find
the photos at  http://www.edgaida.com/elect.html

Any information you can provide will be most helpful.  The music on
the rolls is something else again.  Rags, cakewalks, marches and a lot
of things by I. Berlin!
