Does anyone know what this is?

A little off subject here guys, but I know a lot of you can identify Antiques. I picked this up off of a trash pile about 25 yrs ago while working. It was in the vicintity of Southern Pacific Railyards Station. What I want to know is, is this an old railroad lantern or a Ship's Lantern. Every part on it is Brass except for the wooden handle. And it has a missing bracket on one side that goes to the handle. The wooden handle did not show up in my pics, and I'm too lazy to take another.

any markings on it ???

Looks like a "hurricane lamp" to me.

I have seen examples of this type of lanterrn to be attributed to Polish train lantern's of the 1920's and WWII German train lantern's of the 1940's era. Also, I know of other examples that closely resemble ship lanterns. Take a close look at your lantern and see if there are any markings that might determine a maker or source of production.

Naptha/coal oil lamp. Not necessarily a RR lamp though.
