Many of the top brands from yesteryear have gone away and I'm wondering who knows, or has models of their last production of "serious" saws. Easy to tell with Pioneer as it was their top P-series, 4,5 and 6 cubes (lucky if you have the 6). How about the 50cc Homelite 300 that was introduced in 1991 (I think)? By top brands I'm thinking McCulloch, Homelite, Poulan, Remington, Jonsered.
