did u try schoolhouse electric? we also got some from rejuevenation hardware. both had a good selection of 3.25 fitters if i recall correctly

daisychain, I've looked at both sites without luck so far.

Sorry. Brain blip. Ours were 2.25 and that's the size I've seen on their sites. Has to be pendant rather than ceiling?

Try eBay. Although you may find brass without the plating. Also try residential relics dot com. I have no interest in the site. I've been perusing their sconce shades. Our fitters are repurposed from our previous home. We also got a few on eBay.

You can buy shade fitter adapter at vintage hardware.com. They also do custom, you probably can find local person to make for you as well. Ask at lighting shops and try the location filter on etsy

Here's a whole selection at grandbrass

Great site speaktodeek, but too bad they have no pole pendants at all.

You can make any number of pole pendants from their parts. They don't sell fixtures, they sell the parts to make your own fixtures, custom. Or to modify an existing fixture that uses standard threaded parts. These aren't pole pendants, but are fixtures I made from scratch from grandbrass parts: (the vintage glass globes were ebay)

To make pendants, you just add the appropriate length and finish down rod to the parts mixture (which they sell).
