I have a bunch of used Husqvarna saw parts here that I am not sure what they fit. There are tanks, handlebars, covers, brake handles/clutch covers, etc. Most are at least 20 years old pulled from parts saws. I am not sure what they fit. I will eventually put most in the trading post but of course proper identification is key. I think the tank is from a 272 or similar. The stamped number is 5016991. The handlebar I am not sure on. I do not see a number on it other than on the plastic piece at the bottom and that is 5035863. What do you think?
