trombone catch

  1. Help with a Maker's Mark/Hallmark on k10 Brooch/Pin plz...

    Hi! I have a k10 yg & synthetic pearl cluster brooch, with a trombone catch, & on the back next to the k10 mark, there's a capital T inside a circle. Thought it might be Eugene S. Toner Co. (1902-1914), but now I'm not sure. Any other ideas would be helpful. Thanx!!
