As noted after Wiles-Barre went into receivership in 1895, Aubrey was a principle with Elmira Arms Co., and became the sole proprietor of Elmira Arms in Dec., 1895. John Willys and a group of associates purchased Elmira Arms Co. in 1898, and I don't know what happened to A.J. or the gun production. In 1900 he was living in Norwich, Conn. and working for Colt.
