vintage Koehler Mfg Co MINER'S Battery HEAD LAMP Flashlight in working condition

Description

Here's a vintage battery-powered HEAD LAMP flashlight that was for use by MINERS.  Koehler Mfg Company of Marlboro,Mass made it and probably in the 1960's.  Very well made. Steel battery case holds 4 D-cell batteries and is hardwired to the yellow and black plastic Head Lamp.  Metal clips on both for attaching to the belt and hard hat.  Excellent used condition and works perfectly with new batteries included.    Guaranteed to please the new owner or I'll buy it back.
