This is an ORIGINAL Husqvarna Model 181 Chainsaw Parts List Manual, (1985 printing, should cover all models). This manual has super illustrations and exploded views as well as having in-depth parts identification information for these tough Husky chainsaws. This is in an 4-page, 8-panel format (please see pics). Parts catalog is in VERY GOOD overall condition and it will ship for FREE. Thanks for viewing...........Triple K
