The small Macs are like that too, I have Mini Macs cobbled together with mixed parts from different years / models, they're like the Mr Potato Head of chainsaws.Welcome to the world of McCulloch. Ten Series MACs were built for years and have so many interchangeable parts that many of us don’t know what we have. We call them Frankenmacs. It is thought that there may be more than a few factory built Frankenmacs.
