The two white lights you have are very similiar to the lights that came with the ECO 240 Islander series. ECO (Bennett Pump Co.) probably purchased them from that company. I do not recognize that square base on the bottom of them though, it looks like they were mounted on a high base of some kind but this base could be removed and the light mounted on a pipe. Now the only problem is the condition of the porculain. A perfect light (no chips) sells for about $150.00, much less for bent or ones with chips because they are a little difficult to repair. You might be able to sell them for between $75.00 and $100.00 each.
As for the other lights, similiar ones are still being made today, I have seen them in restaurents over every table. So the resale of them might be a little slow. Can't give you any idea of value as I have never priced them.
When I purchase quantity items such as these, I try to buy them at a price that when I sell one or two, I at least break even, then I don't have anything tied up the rest and am not pressured to sell them just to get my money back.
Hope this helps.
