Trying to gather information on a Swiss gun manufacturer whose stamped weapons carry  “Von ERLACH und Cie”.  I have two examples of work he did on converting the Federal M.1864 percussion to the M.1864-67 Milbank-Amsler Stutzer and also on very early Vetterli M1869 work.  If you have a weapon this person worked on I would be grateful for any information you might provide.
 
  Thank you for your time
