Car Lamps

I'm trying to identify the car lamps that hung in the Florence and Cripple Creek #65 being restored at Sthur Museum by the mounting marks in the ceiling. It looks like a standard adlake style "tree" lamp with two buners.
The burners are located 10 inches from the center of the "base" and have 4 inch chimney openings. The base has a 3/4" bolt in the center and 16 screw holes evenly spaced in a 8-3/4" circle around the bolt. The headlining in gone so I have no idea as to the overall diameter.
Any body out there with something that matches?
I'm looking for pictures to start with, and depending on the complexity of the fixture we may consider producing replicas for the car which leads into another thread...
Thanks in advance!
