This type of windproof lighter did not exist during World War 1, but is often deceptively described as a "trench lighter".
The original design for these Bowers lighters was patented in Austria by Hans Silberknopf during 1925/1926.
IMCO manufactured and distributed this lighter design worldwide for 5 to 10 years before Bowers produced variations of it.
These Bowers lighters are often called "Sure-Fire" because this branding is sometimes engraved on the outer wind guard.
"Sure-Fire" is not a name that applies to a specific lighter model, Bowers used this branding for some flip-top windproof lighters too.
"Kalamazoo Wind Proof Lighter", "Bowers Windproof Lighter" and "Kalamazoo All-Weather Lighter" are different names used for these lighters in advertising.
Bowers began manufacturing these lighter in the early 1930s and produced them for about 20 years. Two significantly different versions were produced and numerous subtle manufacturing variations exist among these.
