Here is a New Old Stock "Striker" or "Sparker" or "Lighter Unit" made by JUSTRITE MFG. CO. to be used on miner's carbide lamps.  I put in a new flint because flints deteriorate with age.  This can be used on most brands of carbide lights, i.e. GUY'S DROPPER, JUSTRITE, AUTO LITE, BALDWIN, SIMMONS, ITP, and many more, both cap lamps and hand lamps that take a striker on the reflector.  Nickel-plated, just as it came from the factory - except it has a new flint.  Winning bidder is to pay $3.50 postage including Delivery Tracking.  Good luck bidding!
