Mike, is there something in particular or indicative that you are seeing about the badge that makes you think it is a reproduction, rather that a good badge that has been plated?
Last week, I saw a handful of badges David S recently purchased out of (Quebec, I think), all good badges, but someone had very skillfully electroplated them all. One standout in particular was a Scully marked Calgary Regiment badge.
Nice looking, like plated medals, but no longer the original finish.
