I bought a saw that was advertised as a Stihl 090. The label/tag that told what model it is was "missing." It looked like it had been scraped off. How can I tell what model it is? The Serial Number is 1233318. The numbers on the underside of the air filter cover are 1106 084 0600 and below this number is 1111 091. Thanks for your help. Bob R
