Vintage Ballou Jeweler Lavender Enamel & Goldtone Leaf Brooch Clip-on Earrings

Vintage Ballou Textured Lavender Enamel Over Goldtone Leaf Brooch and Clip-on Earrings Set - Patent # 156452 (1949) for Ear Clasp Design by Frederick W. Moulson. Official patent document mentions B.A. Ballou & Co., a jeweler and findings manufacturer in Rhode Island (1868-2009). The patent number is the only identifier on the earrings. The Ballou backstamp was not anywhere on the brooch or earrings. An exact brooch was attributed to BSK on Google, but not lavendar color but silver. Family jewelry, excellent condition, locking clasp. Brooch is 2.5" long, and the earrings are 1". Without Ballou's backstamp, this set is listed half off what a signed Ballou would be.
