Hello Jon
I hate to add more confusion but the model could also be a Huntress, a regular contributor to the forum Dave M will have a better idea.
Another problem is that these boats were designed in the 1960s and due to its shape it is very unlikely that your model was ever steam powered. Could your uncle have had two boats?
I hope this is of some help
Paul
