By no means a complete saw but a good start for you if you like to build one. This is the early style. The piston has a small black mark on the exhaust side but can not be felt with the fingernail. It is 50 mm. The bearing feel good and tight. Take a good look at the pictures and ask any questions. What you see is what you get. The brake handle is the only aftermarket part. The rest are OEM. $225 and I will split the shipping
