I'm not sure that I see rounded edges on the locks and frame. I think I just see photo glare. But the shiny barrel bluing did catch my eye. It looks more like a caustic hot blue than a proper slow rust blue. Which can, as Chuck points out, cause problems with the solder holding the ribs to the barrels. And it certainly doesn't do anything good for its value. Hopefully your nephew didn't pay too dearly for this Elsie.
