A former Conn employee said, and this appears to be confirmed by the 1960's Conn Product Manual and other reports, that Electro-D is a similar process to Coprion using non-copper metals. The former Conn employee said that an Electro-D bell was a brass bell, electrolytically plated with copper, and then electrolytically plated with nickel. These descriptions seem to match with each other and the evidence.
