Marked ADLAKE on top, I believe this is the Non-Sweating type of railway Signal Lamp. It is of very heavy cast metal and has a frosted lens on the front and a clear peep hole lens on the back.
I don't have the strength to open this but I looked through the peep hole and believe the burner in there. It measures 16 to the top of the heavy bail handle. It has paint loos and surface rust but the front lens looks good as does the peep lens. It has an area on both sides for attachment to something if needed.
