Some early Symphonions had 'by Ellis Parr and Paul Lochmann' stamped
on the central drive pivot of the disc, clearly visible when the disc
is removed from play.  I have only had access to two of these early
boxes, made ca. 1885-6 and playing discs with single punched 'L' shaped
projections, rather than the normal two-part ones used by Symphonion
until they changed later to the Polyphon type.

If you have access to one of these early rarities please could you
contact me as I am trying to find the serial numbers to work out the
change-over date to the more normal style of mechanism and disc for
my next book which I hope to have finished early next year.

I will need serial numbers of _any_ make of disc box; I only have
around 950 listed so far but I need many more.

Please could you send me:

 - Make
 - Diameter of disc played
 - Model number or description including number & type of combs
 - Serial number

Many thanks,
Kevin McElhone
