The ad certainly conveys a message . . .but it isn't dated. The SN list available on the home page here shows 900 Western Long Range doubles and 1,300 Lefever Nitro Specials dated 1942. But then it's entirely possible those guns were part of a govt contract and used to teach aerial gunnery. Walt Snyder's book shows a few dozen Knicks, also dated 1942. In both cases, it's possible that these were simply the tail end of civilian production before Ithaca converted its entire production effort to govt contracts.
