Authentic converted railroad signal light! Now a lamp with a long, switched cord. Three of the red/green light covers need replacing, they're plastic from when grandpa converted it. Great grandfather worked for railroad/timber companies and acquired it during that time, I'm sorry I don't know the year. The very top piece which would have name/info is gone. Paint is gone here and there.  I'm sorry it's not cleaned, dusty in pictures.  Lock/hing top in great shape, lamp works great too! I've tried to show as much as possible in pics, you can see the bottom where it was cut from the 2 posts that come up through the base, they've been ground a bit. Measures approx 15" x 9" x 9" and weighs roughly 10-15lbs. That's all the info we have on it. :-) thank you for looking :-) please let me know if there's any questions :-) .
