re: #13 Quoth the raven, Covfefe.

That’s what my dad has. He has 8 2-cylinders, including the complete “20 series” - 320, 420, 520, 620, 720, 820 from 1956-1958 - a 3010 with a loader that he uses for his heavy lifting, and a 4020.

Whoa! We had a 620, two 720s, and a 4020 that did most of the work. All were LP.
