Paramount: Informations

In 1934, the William L. Lange Company (New York) debuted the Paramount guitar series - and some of the models were built by the C.F. Martin guitar company. However, LangeŽs company went out of business in the early 1940s. In the late 1940s, the Paramount guitar line was reintroduced and distributed by Gretsch & Brenner (source: Tom Wheeler, American Guitars).
But it looks like no later than 1942, a Paramount line of guitars were built by Harmony.
