Note: There have been recent changes to the Type designations for this style.
The CD 160 was made from retooled Gayner molds that were further reworked by Lynchburg. This adaptation of Gayner molds results in two major variations of the Lynchburg CD 160, primarily differences in the shape of the crown and wire groove.
At least one mold, CD 160 II, Mold 10, was further reworked twice resulting in alteration of the crown profile, CD 160 Type II, Mold 10.1 and CD 160 Type II, Mold 10.2. It is uncertain why this mold was re-worked in such a manner. It is likely that the mold top was damaged in some way and the alterations were attempts to keep the mold in production. It is possible that the alterations were a deliberate attempt to match the profile of its CD 160 to Hemingray's comparable style since Hemingray was the primary competition. It is also possible that damage to the mold provided the opportunity to rework the mold to more closely match the Hemingray version.
Origin of Type II molds. There has been some discussion among collectors about the origin of the Lynchburg CD 160 Type II. Some suggest that the Type II was a new mold manufactured in the Lynchburg shops. As Lynchburg advertised, they had the capability of making insulator molds (see Lynchburg Advertising Brochure), so it is entirely possible that they manufactured new molds for the CD 160.
However, a close comparison of Lynchburg CD 160 Type I and Type II molds with the same mold number reveals identical lettering on the two types, even to irregularities in the shape of letters (see comparison below). This provides rather conclusive evidence that the CD 160 Type II molds are reworked Type I molds to widen the crown and thereby provide a deeper wire groove. That reworking also yields a profile very similar to Hemingray's CD160 No. 14, Lynchburg's primary competitor (see below).
There were 23,358 CD 160 produced in three production runs: between October 29 and December 29, 1923; the week ending April 5, 1924; between February 9 and 21, 1925. Even though Type II is a later modification, it is not known if and to what extent production of the two types overlapped.
All lettering on the molds is hand engraved, with the exception of a few mold numbers that are die stamped. Lettering is fairly even and consistent on all molds, differing only in placement on the skirt and slight variances in size.
There are 5 confirmed molds of Type I and one other reported (Mold 1) but not personally confirmed. There may be more. There are 11 confirmed molds of Type II, with one mold retooled twice. There may be 12 molds total, although it is possible that only 11 molds were used. All Type I molds share mold numbers with Type II. This style does not occur with smooth base.
Numbers in parenthesis have been reported but I have not personally confirmed; other numbers in gray are assumed but have not been reported or confirmed.
