I'm willing to buy or TRADE BIG for these three things. I have an almost complete collection of 60's/70's American lamps. Won't ya help a guy out? Maybe I have something YOU want in trade.
If somebody out there has a metal cap Regency, I'd love to get the dimensions from you. It looks to me like Lava used a modified Regency base for the cap (If you flip a Regency base over and place it on top of the globe, you'll see what I mean).
I work at a technical college, and have the means to machine an aluminum cap.
If I can get the exact dimensions of a factory cap (internal and external diameters, plus the heights of the two steps), perhaps I can machine on for you as well Bryin. I know we both need one for our Empress lamps.
