Was at the F.I.L's over the week end, he had a couple of saws he was a little interested in what there value was as a few people keep pestering him about wanting them. one is an older stihl 051 av its a bit dirty but runs fine. The other is a 2 man mac. it also runs fine. dont know the years of them but I know the mac. is much older then the stihl. here are a few photos. Sorry about the photos of the mac. it was way back in the shop behind a bunch of lumber piles and it weighs about 80 pounds or so and was a pain to try to get it over the lumber piles by my self. so I just took the photos where I could.
