First Base is owned by its directors, based in Central London and was founded in 2002.We are pleased to announce that effective May 26, 2017 J. Barnes Limited has acquired the professional land surveying firm of Elliot and Parr (Peterborough) Ltd. is a firm of 17 professionals and technologists specializing in Land Surveying.Other factors that may assist you in dating are the hinge, flint wheel rivet, and the Cam Spring. Prior to this date all five barrels were evenly spaced.In 1955 the barrels were adjusted so that barrel 2 and 4 were slightly larger than barrels 1, 3 and 5.The first stamp used on the base of the lighter bore the legend "PAT. This was used on lighters manufactured until around the end of 1950. There are many examples of "Pat Pend" cases with "Pat 1950" inserts (see below) these lighters would have been made around the time of the changeover at the end of 1950 using stock cases and newer inserts.The next bottom stamp used is the most confusing of all.
The second has the Squarer 9 and uses a full stop (Period) The length of the stamping is also different, this is most apparent when comparing lines 1 & 2 There is some discussion regarding the date of the removal of the 1950 stamp - see here for details In 1967 both the base stamp and the insert changed.Much research has been undertaken to try to date these and it appears that the first base usually has a nickel silver insert. Some of these have been found on lighters celebrating the 50th anniversary of a Canadian Steel Company which was formed in 1904, therefore it is assumed that the base was still in use up to at least 1954.It is possible that the second base did not appear until 1952. Please scroll to the bottom of this page for details of the research.Codes were not used on the lighters until 1987, so we have to look closely at the bottom stamp and the insert to try to determine the date of manufacture.It is not unknown for Lighters from Canada to to be shipped with Bradford stamped inserts, so this can sometimes be a help.
