I have several bulb catalogs but I lost my old transitional ones
that had both old numbers and new ones for cross referencing.  If
dimensions, base type, voltage and wattage can be given, I can probably
find a replacement if it exists by searching the new catalogs.

Edison type bulbs can be purchased from Van Dyke's Restorers, tel.:
1-800-558-1234.  They are "Genuine Recreations" but I don't know if
they are carbon filament or not.  Not cheap, but if they are carbon
filament, they last a long long time.  Their life is directly related
to their dimness.
