This is a Vintage Delco 6Cyl Distributor I acquired in a Large Inventory of Vintage Auto Parts I was fortunate enough to have purchased from an Old Salvage Yard that had dismantled parts cars since the early 1930's.  I am unable to find a part number or any clear markings on this one. I believe it is Teens or Early 1920's Vintage. The Potmetal Housing has some age cracks and is Broken around the upper cap rim. Can be seen in the pictures. I consider this as a Parts Only Distributor.  FREE SHIPPING IN THE US.
