Railroad set looking for more information on this?

Was the lucky winner of this little Brass tray and Amber glass set at a local estate sale, normally I don't buy brass items but it was an appealing set
Decided to leave as found condition and have been trying to find more information but not really sure what to search under
In talking with a collector of railroad items was told it may have been used in the railway but have no date reference or period other than the match pack that was with it
Any information or help is appreciated
