I have for sale three of the highly sought-after yellow green Sediver glass suspension insulators (11.25" diameter), ST-7712. These have only been found in use in Northern California with the majority of the suspensions coming from the famous Tracy, California salvage accomplished by Jim Decker in 2005. The suspensions I own are part of an older find made at a nearby Stockton substation where the strings were picked right out of the shipping crates. These have been hot sellers for me on eBay at my current pricing and personally my second most requested insulator as a dealer. The suspensions can be delivered to the 49er's Historical Bottle Show in Roseville in December. Price at $150 per disc plus cost of shipping. To ship retail ground to the east coast costs around $45.00. Shipping cost will be less if you live closer to Northern California. All free shipping slots to Springfield, OH are taken.
