This is cool... it is the patent for the design for the vent plate on the Sierra Turbo. There is also a homestead plate on there too. I found the design for either the Homestead Wind or Wind II on there but they only showed it with four blades. In order to find anything you have to mix your search terms. I entered Litco and ceiling fan to get that Turbo vent pattern drawing.
