Hi Keith,  It is also possible that you could have a coin-op that was
made as an electrified model at the factory, unless of course there is
no trip switch where a coin would cause an electrical connection to be
made and some sort of timer mechanism or another trip switch would then
control the duration of the bird song.  Or obvious non-professional
tinkering having been done.

If I'm correct in that assumption, you probably have what Reuge called
model #7420 -- 25" tall by about 12" wide (square-cut wooden base with
floral relief and real gold leaf covering the entire base, with cutoff
corners creating an octagonal appearance) 3-bird (blackbird, canary
& warbler) designed as an electrified, coin-operated unit with a coin
catcher drawer with lock and key.  They were made for European and
Domestic (USA) sale with different electrical voltage configurations
and coin slots of different sizes for the different dimensions and
denominations of European and US coin currency.

If that is not the case, then I'm a little confused because the
cams that control the bird song and the movement of the birds are
generally attached to the base of the main spring housing with the
mechanical lifters above that.  Therefore I would think that in the
electrification process the only things that would be removed or
disabled would be the mainspring itself being detached from the
central winding arbor and removal of the fan/speed governor and the
endless screw.  All other parts could be left as is, and an electric
motor inserted to replace the endless screw and fan assembly.

I have some parts, like the bellows and whistle assembly and the
release gears but I do not have the spring barrel or the fly/fan
assembly.  Please call me to discuss your piece, and if I can't be
of assistance I'll try to put you in contact with others who can assist
you in your quest.  Good luck.
