I recently acquired this insulator among numerous other porcelain and glass pieces. I am unsure of the U-number but I had found examples similar in ICON picture gallery. Some call it a U-913, another called it a U-869 and then another something else.

It is a unipart insulator....all one piece. Color is really nice and condition is exceptional. The date stamp is the only weak spot but is still legible. It says Mfg. May 1931.

It stands about 7 inches high and the largest disc is about 10.75 inches wide.

Sorry but I will only ship this within the U.S. I will take potential buyers in order of the emails I receive. Price is $195 plus actual shipping from zip code 65689 using parcel post of the USPS for a 16.5 lb package. Insurance is at buyers option. I will accept a check or postal money order. I am unable to do PayPal.
