The main difference from a C-100 to a C-101 was the hoodstand arrangement. It split into a transmission type tunnel with a small bracket under the dash panel - the battery sits on this. The PTO arrangement changed as did the deck lift handle. Two side covers finished it off, one hooking over the deck handle, the other being the belt guard.
And yes they had the hood ornament...
