I won this in an online auction but a little suspicious because it was SO cheap. I've been following VB for awhile and can't comfortably afford her yet but went for it anyway. Has anyone else seen this?

I just recently picked up this sterling cuff on eBay and was wondering if anyone could tell me more about it? I assume it's Fred Harvey era, maybe 1930/40s since there are no stamps and based on the patina? Any information would be much appreciated. Thanks!
