My dad had a homelite 990 he'd used falling redwoods back in the mid 1960s. I got to run it a few times bucking big fir trees into firewood. With the 72" bar and a big Doug Fir you could make a cord of firewood in a big hurry. That was a great old saw.
I worked in the logging woods in Northern California a few summers while going to college. One year I was chasing landing and they provided me a couple of Homelite 1050s. They were okay saws, but I wasn't overly impressed with them. The next couple summers they provided Pioneers, don't remember the model for sure, they were great saws.
