an 042 is like an 032 or an 050. nobody wants to run those! big old dinosaurs LOL. i think about it now and the oldest stihl i could ever be happy running is the 038 LOL if i was a stihl guy i'd likely keep it for firewood but i own plenty of huskies that do that job so the stihl takes up room in the shop. i did run this thing a full day a couple days ago though and it does run very well for an older saw. 28" with a square ground chain and she was sling'n chips quite a ways. it also has the wide discharge clutch cover.I have an 042 here also ,odd looking saw ,looks like a horseshoe crab ,cant give that thing away .
