I don't think you'll ever see another one of these. It is a number plate from the front of a locomotive that says "924". It is in decent shape (after being on the front of a locomotive for years, it certainly could be worse

)
It is translucent milky plastic with black letters and is about 2.5' x 1' (the tiles in the pics are 1 foot square). Light shows through so it would make a super garage light or, if you're a train guy, something to light up your basement near your layout. The one pic where I'm holding it up has the light shining through from the back.
