Auction is for a rare good condition GRIFFIN LAMP CO. stop light with mounting bracket. The lens is marked GRIFFIN LAMP CO. HAMILTON OHIO MODEL 200 and it is approx. 6 7/8" across and is GLASS. The case is marked GRIFFIN MODEL 200 and has some rust but I bet she'd clean up fine. Super nice old stop light with glass lens - and it works! Thank you and please see my other vintage lights listed.
