here are the 2 Richard Hubnuts I got. one on one dig, the other on another. but they are very different. and neither of them are stained. They are made out of different glass. pretty cool. one even came with the stopper!!!
That's a nice lamp and came out really clean, you should be able to find a brass collar which you can use plaster to cement it to the top, then get a burner and chimney which are easy to find and it will be complete, the collars are standard for almost all of the kerosene lamps. It looks like it probably takes a No. 2 collar and burner, the larger size. The metal thing looks like an industrial light shade.
