Antique Colt gas lamp not sure how they work I think it's missing a bottom cage from what I seen on the Internet. But pretty much everything is there. I cleaned them up as much as I could the striker ignitor and all the stuff is there. These are in the best shape I've seen yet. You can't find them in this good of a shape like I have.
