Vintage Chatelaine Silver-Tone Brooch with Multi-Chains and Key & Tassle Charms

Unique vintage Victorian inspired Chatelaine double brooch featuring multiple intricate chains, key and tassle charms in a silver-tone finish. Lots of classical details on brooches but from the swirl (cinnamon bun) chain I'm guessing 70's but really not sure - last photos are the only other examples I could find online. From a smokefree but pet friendly home. I use recycled shipping packages for the environment.
