New guy here. Can any of you Stihl experts tell me if there are any visual differences between a 440 Mag vs the 460 Mag? My friend just snagged one out of the pawn shop today but the model number tag is missing from the top cover. The filter cover still has the "Magnum" decal. The saw has the new style filler caps, comp release, single inner dog, and 4 bolt muffler cover. It's smaller than the 660 for sure and larger than the 260 .... has to be one of the above models .... yes? I told him to grab it or I would .... hope I gave him good advice. Just like to know for sure which model it is. Would the serial number be any help ...... #160399972. Pawn shop thought it was a model 048 .... it's much newer than that.
