1950's Fruit Salad UnSigned Pin Brooch Dragon's Breath Schreiner

Gorgeous vintage piece - entirely prong set all glass rhinestones. A little round dragon's breath and a round Givre. All the stones are bright and crystal clear. Measures 2.75" both ways. Now for the back plate - not so pristine. I made no attempt to polish it - I will leave that to the new owner. If you appreciate this look - this one's a beauty. Who made it? no clue - perhaps Weiss or Schreiner? If you can nail it down give me a hollar and I'll add it.
