I just acquired this really cool 7 1/2" wide Fred Locke glaze-weld from a worker at the Victor factory. According to him, it was dug from under a building at the plant during construction about ten years ago. This specimen appears unmarked . He had a second one with a clear 7-1 marking stamp (not for sale!). This insulator was cataloged as Locke's #4 and was prominently shown in all of Fred Locke's catalogs from 1900 onwards. U-932 specimens were made in both brown and white . Broken white examples have been found in the victor dump . Robert Winkler reports that he has seen photos of white U-932 specimens in service in Michigan some place . The top shell is the exact same shell as the top of the M-2332 [id=122357975] wile the inner glaze-welded skirts are those from the U-926a . These insulators were made in two part molds and have a mold line over the crown. Early versions from before 1902 had applied crowns. A very early version of the Locke #4 exists that was produced by the Electrical Porcelain and Manufacturing Co. It is owned by Elton Gish and has been assigned U-927 There are currently only three examples of the U-932 known . [id=197204057] for a view of the underside of this insulator.
