lot of vintage tin plated metal embroidery hoops, needlework frames round & oval

Lot of vintage embroidery hoops, all metal (tin plated steel, I think?) with cork. There's one 7" diameter round, three 6" diameter rounds, two 5" diameter rounds and a oval frame which is a little bent, but would work for heavier fabrics.

These are nice and clean without rust spotting, cork looks good on all. Most of these were never used, from the look of it.
