I just scared up another one of these for my someday going to get them going collection of the early round hood ones. It looks like it has lived in the fence row for a good part of its life. None the less, got to get them when I see them. The model # is 917.60616 and the serial # is 11010. Would anybody know whether this is a 59, 60 or 61? I am somewhat confused on whether all the early ones were the same model unless it was an electric start. Also, it has the worn original decals on the hood, along with these, there is a large number 7, this also makes no sense to me, but it looks about as old and worn as the rest of the decals. Much thanks to anyone with insight. Sorry for no pics.
