I'm looking for some General Electric D23 candelabra screw base Christmas bulbs. They were sold under the names "Satin-Glo" and "Satin-Bright" a few decades back. They have a satiny, almost irridescent finish to them when off, and they look a lot like common, opaque C7 1/2 Christmas bulbs when on.
On very rare occasion, I'll find a vintage string of Noma C7 1/2 lights with a few of these satin bulbs mixed in with the ordinary opaque painted bulbs; but it seems to be a bit much to buy an entire string of bulbs to get one or two D23's, knowing they might not even work. But I can't seem to find anyone who sells just the bulbs. Ideas, anyone?
