I am not familiar w/ Stihl stuff, so what you see is what you get. This appears to be an oem cylinder for an ms250, the plating is pristine... did someone rechrome this? I dunno. its nice lookin. piston included, but no rings for some reason. I noted that one circlip is loose, the other is in the piston. some plugs and gaskets and a few misc things for 250's.
don't know much about this stuff, so please, get it gone, $100 shipped lower 48 paypal ff.
