Western Arms Corp was the company owned by Leonard Frank Allen. Leonard Frank Allen had started Replica Arms, in El Paso, Texas in 1962, with the first Colt 1847 Walker replica, made by Armi San Marco. In 1965 the company was sold and moved to Marietta, Ohio, with Ken Phelps as President. In 1973-74 Replica Arms was bought out by Val Forgett and Navy Arms.

Meanwhile, in Santa Fe, Allen started Western Arms Corp. in the early 70's. In 1980 he found himself the subject of a lawsuit brought on by the Olin Corporation (Winchester) for trade name infringement with the company name, Western Arms Corp. Olin Corporation owned Winchester Western ammunition, so Leonard Allen was forced to dissolve Western Arms Corp in the late 1980's and two separate companies were then formed, Allen Firearms Company and Western Gun Stores, Inc. It's the Western Gun Stores that folks confuse with Westerner's Arms.
