We really must have a SimV pioneer fly-in one day! We already have an Antoinette, Bleriot, Demoiselle, several Curtiss designs and even a Voisin Hydroplane.
You could base your model on a Curtiss June Bug, with which the Silver Dart shared the basic design (I believe that the Dart was a development of the June Bug design, anyway), and "correct" based on the slight differences from the available photos.
Thanks for your help guys. A big thanks to gryshnak for sending me that link for the model. The company who makes the model are being very gracious in sending us a free model kit to assist with building.
