Stihl 25” Rolomatic ES light bar and Stihl 33RSF skip chain. 3/8” and .050, large mount (3003). Used for 2 tanks of fuel, and realized I need a longer bar. The chain was bought new with the bar, and was lightly sharpened once between fueling. Used in clean wood with no damage. Nice and lightweight, barely used, and balances the saw really nicely!
