This is a hopped up version of the Mac series 87cc version frame saws.  Several of the ones I have had have come from my local area in Northeast Ohio and a few from the west coast area.  These saws have been sold nation wide and with some luck can be found in most to all areas McCullouch's were sold.

​     Mechanically speaking these are easy, straight forward to work on and maintain.  Parts are shared with a whole pile of like models and are still out there.  I have had both Mac flat back carbs and Tillotson carbs on them.  By far I prefer the Tillotson carb.  These are heavy saws compared to today's models but this doesn't lack any power especially the top end with torque. 

​     All in all a nice vintage saw to have in any collection.  I recommend a 24" bar with full comp .404 full chisel chain for some real fun!
