Here is a complete collection of all transposition styles produced and sold by Fred Locke in the 1894 -1908 era .; left to right; U-192, n.n.,( Lima Insulator Co.) 1904-08 ,I personally found a fragment of one of these in the Lima dump in 1998 ,A fairly common tramp;

U-225 a&b, n.n( Lima Insulator Co, listed in the 1904 Lima catalogue) (cir.1904- 1908 ) Only about two dozen of these exist . U-220 a&b marked Fred Locke, manufactured (cir 1902-1904), A scarce tramp found primarily in the northeast along railroads ;

U-192a, brown, marked Fred Locke ,( cir 1901-1905), Later specimens are often unmarked, found widely distributed in North America and the Victor dump.;

U-192a, white, marked Fred Locke, (cir 1902-1904), Four good marked specimens of this insulator were found in British Columbia, Canada in the 1990s and a few damaged ones were dug in the Victor dump. at least one of which was unmarked.;

CD 202, Fred Locke the most common Locke tramp ,(cir 1899-1910), the "F.M. "was blotted out on later specimens produced after 1904. These are a Brookfield product.;

U-196 Ink marked Fred Locke, This two part glazeweld dates from 1898-1899 and was Freds first porcelain tramp . A handful of these were found in British Columbia and fragments have been found in the Victor dump .Some collectors speculate that these were one of the first insulators produced in the Victor plant. Specimens are rather crudely made wet process porcelain., differing from the finely made products attributed to the Electrical Porcelain & Manufacturing Co.;

CD 204 Fred Locke & Co (cir .1895- 1898) Freds first glass tramp with a cross grove in the top ! A very absurd fragile design produced by Hemingray . ( broken specimens were dug at the Hemingray dump) A handful of unembossed examples of this tramp exist that may have been produced by a different manufacturer in 1894. or 1895 .Some embossed examples of these were found in the northeast and a few on an 1898 line in the area of Nevada City, California, This may be one of the earliest unipart glass transpositions produced in the U.S. Very few examples of CD 204 exist without damage.
