Hi Catherine, out of curiosity I checked out Lady Penhyrn on Wikipedia and there is a few details on there some being easier to live with than others. Yes, she did deliver convicts to Australia, but she was supposedly built for the slave trade. The biggest and maybe best model shop in the U/K here is probably Cornwall Model Boats, which has a very large stock of models based around the 17th and 18th centuries. I hope this information helps you to find something suitable for your Dad. Regards, Gary.
