Hi all, new to this site and somewhat new to chainsaws. Picked up an early Sears Lightweight Powersharp 3.7 saw (roper made) It has a roller nose Bar on it that is unmarked. Looking to see what would work for replacement on this older bar. It was heavily worn on one side. I've decked it and its usable but I'd like to get a modern bar for general use. Saw runs great and is torquey...for 40 bucks I think I scored for a complete running saw, case and original toolset! I appreciate any input given.
