My Buddy, a craftsman guru says the only reference to "2.7A/VL and chainsaw" comes up as Sears model 271-358260 made by Kioritz Corp. = Echo . Might not be yours though
Sears still lists parts for it on partsdirect. You might be able to cross reference to the OEM for more info. I googled the craftsman model number... got 2 hits
So I guess if no one here can tell you the Echo version, you can try to figure it out with the Echo part numbers listed on the sears website to see which saw/saws from echo they fit on. They seem pretty rare.
