Hello Steve
Not much information so I googled the model. If it's the kit I doubt it will be worth very much as it is unlikely to be a museum piece.
Old models can in my opinion be ruined by new painting so some photos would help. Static models don't have to have sails and often they look unrealistic unless done very cleverly. Furled sails are easier to do.
You will get more replies if you give more info.
