Interesting. An auctioneer handled my Aunt’s (by marriage) estate & quoted me $300 so over the phone I offered $250 & he said ok. I went to pick it up and my mouth dropped as I was expecting black but it was celery green with an aqua tone case. Has 1961 original sales receipt ($100 plus tax). Barely used so I feel fortunate. Later he saw me & told me (with a grin) I had stolen it for that price but he said since I was a niece it was ok.
