I do not, I would try to get in touch with a contact at Princess Yachts. Perhaps a Princess dealer can be of assistance as well. Who knows they may be helpful as you may be in the market for a new Princess some day! Well, at least that is how I would treat it if I were a dealer or manufacturer.
May be check also for 440, as the model as called Princess 440 before the two feet bathing platform extension, and I would imagine very little has changed.
