Vintage Blue Kopp Glass Railroad Signal Switch Light Lantern

The glass is a flat glass, not Dome glass like most others.

Kopp glass noted on back

Lens 5 3/8” D 3 1/2” F both noted on back

Super clean glass, no chips or cracks anywhere!

I also have up 1 more blue, 2 orange, 3 red(1935), 1 flat clear, and 2 large clear lantern glass!

Thank you and happy shopping!
