R.H. Gunnis -that's the correct name. However earlier you mentioned Gunniss.
I think the year is 1901
You're right. One 's'. The article is old and small, and my eyes are failing me.
This was indeed from 1901. The article I found it in calls it a "Burlesque Auto-Locomotive". I don't think the builder called it that, but I will likely be proven wrong about that, too.
I'll post the article tomorrow.
