#1253 Robert Muller Patent Model. Black composition. Threaded interior.
On January 6, 1905, Robert Muller applied for a patent involving a specific type of material used, and manufacturing process for insulators. The patent was issued to Muller on October 29, 1907. This is a United States patent, issued to Muller, who resided in Munich, Bavaria, Germany.
Patent models for insulators rarely surface for sale, this one complete with it's original identification tag, created at the patent office.
The insulator measures 2" tall, and the tag is 3" in height.
Insulator in excellent condition. Paper tag is aged and rough around the edges.
Dick Bowman collection.
Update: 1:30 P.M. Thursday, June 17. Second photo added, showing a bottom view. Note the exceptional detail of this small model, including the threaded pinhole. The model has the same appearance as that of a larger, actual insulator.
