Homelite's first gas powered chainsaw. This is a big round barrel of a shape.  It is heavier than it looks and seemed to do quite well in sales as Homelite built many of them. The shape/style carried into the next 4 saws they threw down the line. I have a couple 20 MCS's and between them hope to put together one really nice saw. I will add better pictures when that comes to fruition.
