set of six vintage cranberry glass bowls, weighted bottom hand blown glass

Beautiful set of six vintage cranberry glass bowls, about 4 3/4" in diameter x 2 3/4" tall. All six of these are in very good condition, a lovely set showing very little wear or use.

These aren't signed and I haven't been able to find out much at all about them - they look hand blown to me, but I can't say for certain when, or where. 20th century vintage I believe, not antiques.
