Sarah Coventry Old Vienna Pendant Necklace with Detachable Brooch/Pin Gold Tone

Vintage 1970s Old Vienna pendant brooch set. Pendant and brooch hook together to make one pendant or unhook the brooch for a 2 piece set. Necklace measures approximately 24" L. Small oval pendant measures approximately 1 1/4"L X 1"W. Oval Brooch measures approximately 1 3/4"L X 1 1/2"W. With brooch attached to small pendant, pendant measures approximately 3 1/4" L. Necklace is in good vintage condition. However due to age and being worn there may be minimal wear on chain. I also noticed minor wear on the back of pendant and brooch ( refer to photos). Signed SarahCov on back of pendant and brooch.
