I have the deluxe model with no AV, but this is a real deal countervibe!! These saws were pretty high tech performers in their day! Hope it goes to a good home and is turned into runner. Some oil parts check valve are NLA, does the OP know if this one had a functioning oiler? I need a set of crank seals for mine but won't put my hand up for this saw. It should go to someone who will use it and is in need. They go well and have enough grunt.
