I was given a 452LV yesterday. at least i think thats what numbers were on it.It was in a friend's grandpa's barn.He passed. They are having an auction.I dropped it off at my saw guys house. It looks to be in good shape besides the broken pull cord. I told him to fix cord and check compression. I did a lil interweb research. It looks to have been produced 1975-1983. I was built in 82 lol. What should I do with this saw?
