Serial number indicates made in Germany. I used this saw for about 10 hours had some mods done then used it for about 25 more hours.Starts, Idles, Oils, and Revs to full throttle like new. These saws are best run at 50:1 this saw has always been used with only Stihl Ultra 2-cycle Synthetic oil (non-ethanol gas) and Sthil bar oil. Has 54mm meteor cylinder and piston with caber rings (IMO the best) and a few other mods that I can not remember (small engine shop did the mods). This saw is no joke and NOT a beginner saw. Oregon PowerCut Guide Bar 32 with Sthil cover and I'm including a chain for free (may need to be sharped). Thanks for viewing my listing and have a great day!
