The number one give away, Stihl bars don't wear paint of that easily. I cut better than ten cord with my 390, and the bar looked brand new.
Then he didn't even try to clean it up for pics., sends up a red flag to me.[/QUOTE
Attempting to cut hard, dead wood with a rocked or dull chain will cook the paint right off the Stihl bar. My ex BIL did this till the bar warped, or perhaps he bent it some other way, but I consider it a testament to the 290 that the saw is still fine after some serious homeowner abuse. (with new bar and chains of course)
