Hi Robbie,  Give AAMSCO, up in New Jersey, a call at 1-800-221-9092.
Ask about their Heritage Series "Ferrowatt" reproduction lamps.  They
may have a minimum order of one dozen bulbs.  They stock the 1919
Tesla, 1920 double carbon loop, 1900 horseshoe, 1910 squirrel cage, and
1930 art deco styles.

Most of the styles are available in 30 and 60 watt sizes and they
really look nice.  The glass bulbs even have the top exhaust tips.
The last ones I bought ran around $10 each, but when used on a lamp
dimmer they should last indefinitely.  I have 6 of the 60 watt 1910
squirrel cage style left, brand new in the box, and for sale as one lot
for $55.00 postpaid if anyone needs them.

Regards,
Roger Hughes - Texas
