It's tiny, whatever it is. Here is a slightly larger view, but if you'd get a better picture, answers might be easier to find.
It's a small brass item, maybe 3" tall. I was thinking possibly from a very early car. Possibly something to do with the side curtains or kerosene headlamp.
As mentioned , more pics. But clean it up first, pics from different positions. Looks like it has a cradle to hold something in place. Is the end (somewhat pointed) is removable?
In addition to being addicted to the old car hobby, I also enjoy metal detecting old homesites and such. I am a member of an online metal detecting forum and there's a sub forum for unidentified items found with a metal detector. Someone posted the item the other day and hadn't received a definite answer. We're going with a valve from an antique coffee urn. Thank you one and all for responding.
It’s a piece of alien technology that quadruples the horsepower of an internal combustion engine… DO NOT press the button!
