I collect mostly vintage Bulovas but I acquired this Elgin a couple of days ago. I thought I knew a little about Elgins but this one has thrown me for a loop. This is the first Elgin I've come across with a copper colored movement with no serial number on it. I'd like to know a generalized date period for it. I think it's newer than I originally thought. I thought it was from the 50's when I bought it.
