Meriden only produced about 79,000 sxs guns under their own name. They also produced the Berkshire which was sold through Sears. The serial numbers of the Berkshire appear to fall in with the Meriden, however, I have recorded too few to be sure. I keep waiting to find a Meriden and a Berkshire with the same serial number. They never produced a boxlock, at least not that I can verify.
It is unclear how many pistols or rifles they produced. I have never seen even a guess at production numbers. I do know their pistols keep showing up under various names, even Smith and Wesson was marketing them.
As far as high end guns. Meriden did offer some, but nothing close to the Parkers, Lefevers, Ithacas etc.

With the current "brand interest" (LC Smith, Fox, Lefever, Baker, Parker sites) It would be interesting to get some of the "specialists" to speculate about custom builds and the accuracy of serial number lists.
