Very nice, interesting piece of history. This is definetly a "Muskoka" boat, wonder if this is an old "Greavette" model.
Info doesn't say much, but it appears to possibly have a later outdrive.
i use to see some of those style boats when i use to dock in kingston, confed basin, for the summer. there is some sort of big show every year for those boats on the american side and you really see them about that weekend. there is another one i use to see on the bay of quinte once in awhile with an older couple driving it. you really have to appreciate the up-keep for one of them. it would be like a never ending body job to us car guys. "a labor of love."
the poop is similar styles but bigger were rum runners during the era.
