Schooner restless : Looking for info

I wonder if you can help. I own a Schooner now called Restless. Her original name was Avesta. She was supposedly a Howard Chappelle design, built somewhere between 1930 and 1960 . Do you by any chance have any record or info regarding her. She is 41 ft on the deck. I found her in South Africa . She is now in Florida and has completed a circumnavigation so she means a lot.

Thank you very much, hope you can help.
