Yesterday Robbie asked about a source for carbon filament lamps for
an orchestrion.  The best source for reproduction antique bulbs I have
found is:

  AAMSCO Lighting, 100 Lamp Light Circle, Summerville, SC  29483

  Ask for Mr. Bob Rosensweig.

Many 'reproduction hardware' places sell a carbon filament lamp,
but these are not very authentic looking, being in a modern "A"
(pear shaped) envelope, something like AAMSO's model 1920.  AAMSCO
model 1900 is an 8 candle power carbon lamp in the correct "S"
envelope, with straight tapered sides and exhaust tip on the outer end.

However, for most coin pianos, like Seeburg, these lamps may be
inappropriate.  After 1906 the carbon filament was replaced by an
uncoiled metal filament which zig-zagged up and down between two
multi-armed wire spiders.  This 'squirrel cage' Mazda lamp, in the
"S" tipped envelope, was the usual format up until 1925, when the
modern frosted "A" shape lamp was introduced.  People my age may
remember seeing such bulbs still in use, when they were kids.

AAMSCO model 1910 (120 V, 40 watt, 38 candle power) is a perfectly
authentic looking reproduction of this style.  Bright enough to give
useful illumination, and having an average life of 2500 hours, they
might be more appropriate for coin pianos.  Their period of use,
1906 to 1925, coincides with the heyday of large case coin pianos with
art glass fronts.

If you really want a fainter glow, you could ask Mr. Rosensweig if they
still have any of their 240 V, 60 watt squirrel cage lamps.  Although
not in the current on-line catalog, they had lots left over when I last
inquired.  When run at 120 V, these have a fainter orange glow, about
the same as an 8 candle power carbon lamp, and they last practically
forever.
