Since the bench is currently clear I've been working on a mainspring conversion to a coil spring for the 1858. So far it's showing some real promise. It's been interesting getting the operating angles sorted out but so far so good. Not going show photos until I get most of the bugs worked out. Once the Remmie conversion is figured out I am gonna tackle the open tops and see what can be done there. Let me know if anyone is interested in this conversion. I am really intrigued by the possibility of fitting this set-up in a Walker or Dragoon.
