Over a million No. 36 CD 162 were made by Lynchburg (1,097,532), making it second only to the NO. 10 telephone insulator (CD 106) in total production. Lynchburg CD 162 occurs both with and without drip points. However, only about 3% of the total production of CD 162 were smooth base (35,000).
The Lynchburg CD 162 was made from both Gayner and Brookfield molds, both of which were extensively reworked during the course of production. As a result the story of the CD 162 is complicated.
The CD 162 was one of the first, if not the first, insulator styles put into production at Lynchburg. William Gayner had brought molds for the CD 162 with him from Gayner and these, crudely re-lettered for Lynchburg, were likely part of the first production runs. However at some point, Lynchburg also acquired Brookfield CD 162 molds. There is no record of how Lynchburg obtained these molds. Brookfield had stopped production in late 1920 or early 1921, and we know that Lynchburg obtained two Brookfield Kribs automatic insulator presses. So, it is likely that Lynchburg acquired the Brookfield CD 162 molds, along with molds for the CD 102 and CD 252 (and possibly CD 251), from the defunct company, perhaps at the same time as the Brookfield presses.
After the demise of Brookfield, Hemingray Glass Works was the dominant producer of glass insulators in the 1920s. The CD 162 NO. 36 had to compete directly with Hemingray's immensely popular No. 19 (Lynchburg used cuts of Hemingray insulators in their advertising price lists). Yet both the Gayner and Brookfield molds had slightly different profiles with narrower wire grooves than the Hemingray No. 19. In the case of Gayner molds, the wire groove was very narrow and shallow, which made it more difficult to attach and hold wires.
So, to make the CD 162 more functional to compete with Hemingray's No. 19, Lynchburg reworked both sets of molds to widen and deepen the wire groove. This modification gives the reworked Lynchburg CD 162 a unique profile among CD 162s. The Gayner molds were reworked twice, first to widen the wire groove to about the same size as the Brookfield molds. They were subsequently reworked a second time to further widen the wire groove to the Lynchburg profile. Since the Brookfield molds already had a slightly wider wire groove, most of them were used without modification. However, two Brookfield molds were reworked to the wider wire groove.
As a result of these modifications there are four basic types of Lynchburg CD 162. Since this reworking significantly altered the shape of the insulator, these are listed as separate types rather than as mold variations.
A few of Type III and Type IV molds were retooled to strengthen the lettering or to thicken the lower part of the skirt, which gave the lower skirt a slight outward flare.
The Brookfield molds used by Lynchburg were not all of uniform size usually varying in the height of the crown. As a result the overall height of various molds can vary as much as 5mm. Since this is a feature of individual molds typical of Brookfield (much like the CD 112) there is no attempt to classify the Brookfield mold Lynchburg CD 162 by height.
Lynchburg produced 1,097,532 CD 162. They were made throughout Lynchburg's history, and along with the CD 154 No. 44 were some of the first and last insulators made by Lynchburg. All lettering on the molds is hand engraved, with the exception of a few mold numbers that are die stamped.
Accounting for the number of CD 162 molds used by Lynchburg is complicated by extensive reworking. Some of the mold numbers listed under different types are the same molds reworked. The following list is incomplete and includes only personally confirmed molds (see chart below).
Type I: 11 molds, former Gayner, one reworked (12 possible)
It is possible that the 10 original Brookfield Type II molds plus the two original Brookfield Type IV molds comprise a single 12 mold set for use on the 12-mold Kribs insulators presses. That would suggest that Lynchburg CD 162 Type II, Molds B1 and B2, as well as Mold B13, all of which remain unconfirmed at this point, may not exist.
In the menu below, the molds are listed with the Type number (I, II, III, or IV), with G for Gayner molds or B for Brookfield molds, followed by the mold number. In the individual mold listings, there are notations indicating whether the mold occurs in more than one type. This is one of five styles of Lynchburgs that occur with SB (along with CDs 122 [unconfirmed], 164, 205, and 251 [unconfirmed]). Molds below in parenthesis have been confirmed but lack photos; molds in gray are assumed to exist or reported but have not been confirmed.
