Description

Koehler permissable flame safety lamp coal miner’s lamp No. 209 made in USA
Auction find, as is. No idea how to test for functionality, no defects noted. Please see and zoom in on photos for details and condition. I believe this is a vintage or antique mining lamp. Have not attempted to clean or restore, would say it's in good vintage condition. Happy to address any specific questions. Thank you for your interest.
