Stihl 031 av Chainsaw cylinder

[DisturbeD]

I'm just wondering if this 031 cylinder and piston are OEM or something aftermarket. I've looked at a ton of cylinders on ebay however most sellers are terrible at taking pictures. The only stamping I can find on the cylinder is ck on the top and ck827/1f I believe on one of the sides. I'm use to seeing Mahle or stihl stamps but I've not ever stripped a 031 down for parts. Which I didn't with this one either I received it in pieces already with no intentions of reassembling it.

Usually the aftermarket stuff has no markings. Looks oem KS to me.

Well thanks for the information I like to be sure before posting things for sale. If it was aftermarket I wouldn't even waste the time.
Yeah I think I've only bought 2 chainsaw so far with aftermarket cylinder kits. The 461 kit had no marking and I can't remember on the husky 365 I'd have to look.

Some of the old AM stuff was actually made by KS but they did have the" + "symbol on them.
