J.P. Sauer & Sons of Eckernforde, Germany made all, to my knowledge, of the various firearms imported and sold by Hawes Firearm Co. of Van Nuys, Ca. I believe that Hawes Firearms was in and out of business in the 1960,s. I, by the way, have a couple of their single action revolvers and find them to be very good guns. My belief is that they are probably about as strong as a Ruger. J.P. Sauer & Sons only made cartridge firearms. The Hawes Firearms replica black powder percussion revolvers were made in Italy by Arimi San Paolo, Rigarmi, and another unknown Italian manufacturer using COM marking. Some were marked just "Made in Italy" along with the Hawes Firearms markings. Dr. Jim L. Davis
Hawes Firearms were manufactured by a company in Germany around the late 60's to about 1983. They were a fairly decent gun, but not in the Colt or Smith&Wesson class by any means. They are not a collectors item so they usually sell for about $150 depending on condition and model.
Between 1973 and 1981. These were made by JP Sauer and Sons in Germany, and imported by Hawes.
