My daughter inherited this gun from her Dad's estate several years ago not knowing what it was. I told her to bring it over and lets take a look at it. It is a Dart 1858 Remington replica. From what I can gather these were imported by EXCAM, a Hialeah, FL. based company that stopped imports in 1990. I had never heard of Dart. I disassembled the gun, did a cleaning and it seems to be in good shape. Very strong mainspring and a stiff action. About .010" endshake and the barrel looks good. Is anyone familiar with this gun and how common (or not) it may be or have any info of interest on it?
