In February last year I had a chance to discuss Camillus tang stamps with Tom Williams.
For those of you who do not know, Tom worked for Camillus for 30 years. His mother retired after 50 years working at Camillus and later went back to work 5 more years eventually retiring as a department vice president. He was also the Company Historian for Camillus.
Tom basically has Camillus in his veins.
Even Tom is not cut and dried on Camillus tang stamps, with a few exceptions. Tom told me that the four-line stamp: CAMILLUS/CUTLERY CO./CAMILLUS N.Y./U.S.A. was in use prior to WWII. From what he said it sounded like the 4-line was used in the 1930s and probably earlier.
After WWII the third line, ‘CUTLERY CO.’, was dropped and the word ‘CUTLERY’ was not used again except for the Marine Raider Stiletto reproduction and the A425 (USCG knife) reproductions of the 1990s. In both reproductions the original tang stamps had been saved and were used on the reproduction knives.
With the exception of those two reproductions, the third line was dropped in 1945 or 1946; he was not certain which year. However when the bomb was dropped in Japan, Camillus was working on an order of 250,000 ML-K knives for the military. The government cancelled that order about 3 days after the bomb was dropped. They did use those blades that they had stamped as well as the other parts in knives made after the war. They didn’t throw away the blades with the four line stamps. So technically there were knives produced or completed after WWII that had the 4-line tang stamp. But the blades were made prior to the end of the war.
It is my understanding from what Tom said that the 4-line stamp was used well before the start of WWII.
