Re: Is This a Remington Revolver ?
"there should be threads showing where the barrel protrudes through the frame and meets the cylinder."
True for the later models but the Beals and very early 1861's (Army and Navy) have the frame straight in that area and the barrel threads don't show.
That is one thing that about threw me, as I don't know of any modern repro of the Beals, only of the so-called "1858" model, which was not actually made until 1863. The "Model 1858" name is modern, taken from the last patent date. Remington actually called the .44 the New Model Army Revolver, and the .36 the New Model Navy revolver.
