Chainsaw Repair

First roller noses I've ever seen or even heard about this small .I have a couple sprocket noses for the S-25 and one hard nose my first model came with .On the hard nose I've lost count of how many chains I've been through and how many times I've dressed the bar .Both saw and that bar are still fine .This is on a saw that was made mid 1970's .--and some people try and say all Pouian ever made was inferior --Ha.
