Vintage Noah's ark silver brooch animals 50's 60's

Beautiful silver Noah's ark brooch, this is an older one, but in great condition! The pin is slightly bent but that doesn't harm this at all. This has three animals dangling from the ark boat. It's a bit over 1.5" tall and just a little over an inch wide. This has no designer stamps or marks that I see, I'm not sure if it's silver plated, 925 sterling or what, it's not been tested. This is a vintage estate find. listing vintage and new jewelry daily, bundle and save, reasonable offers welcome.
