Made in U.S.A. 1900s - 1960s. The first Addometer was made in 1927. This looks to us like an "early" one, but we're not experts. Guestimate it's from the late 1920's to early 1930's.
The Addometer was very popular and together with competitors such as the Lightning Calculator were produced for many years until cheap electronic calculators were available.
