I will bet that my "little XL" saw that is all metal is a tad older than yours. Mine is blue and shows XL-101. The guy who gave it to be said it's at least 60 years old, circa 1960. I got the engine running fine but it has a bar oil leak from the tank that cracked possibly 45 years ago. So, it's an old shelf queen.I have just about everything to build my little metal XL saw. Found a new bar and chain for it but I will still need a db valve and maybe a better air filter.
Regardless, I still like to hear it now and then. By far, it's the loudest saw that I own.
