Andrew Fyrberg it is. The revolvers were made by Meriden. There is actually little in common with S&W revolvers except general exterior appearance.
Fyrberg is best known as a designer for Iver Johnson, most notably of the "Hammer the Hammer" safety device, the first transfer bar revolver safety. He also designed, in a less glorious moment, the Davis Warner "Infallible" pistols.
Those revolvers resemble the "Secret Service Special" revolvers also made by (among others) Meriden, and also a resemblance to the U.S. Revolver Co. hammerless, made by IJ. I have not found what connection, if any, there was between Iver Johnson and production of the revolver bearing Fyrberg's name.
