I am going to start with the last undated lighter as this is the easiest to date.This lighter was made between 19 and is identifiable by what is known as the "Full Stamp".Starting to look at the base stamps in detail, we see below 4 bases that at first glance appear very similar.By carefully aligning the lighters to a common (Red) base line we can start to see the small differences.In the first the base line of the "B" intersects the two "P's" almost exactly then intersects the "M" just beyond the midpoint.In the second picture the same line touches the end of the first "P" and misses the "M" completely.

Some important points to note are the shape of the "3" within this patent number, some lighters have a round top 3 whilst other have a flat top., This was when the "Canned bottom" (where the base of the lighter is indented) was introduced, and all lighters made before this date had either a flat (1933-1942) or a round (1942-1945) bottom.These earlier lighters are quite rare and will be covered on a separate page.Experiments were made using different types of steel and different angles of cut. The result was that the former "cross cut" wheel was discontinued and a diagonal cut wheel was introduced.The next major difference is the hinge, between the two halves of the lighter case.
