We know that from 1901 to at least 1909, Hopkins & Allen were making the box-frame doubles, both hammer and hammerless, that they inherited from Forehand Arms Co. So these side-plated guns must have come from the very end of the W.H. Davenport Fire Arms Co.'s life and passed on to H & A in the teens. I was under the impression that Marlin bought the remains of H & A, so how did the double that looks like this get to Iver Johnson?
