Excellent condition. Mostly used as a hobbiest more than daily pro use. Nice cross section of pilots and stones to cover little stuff and all the performance heads.
Pilots are in excellent condition and tight fitting on the driver motor. Some are even new. There is a selection of spare pilots that are missing pieces but still can be used in special cases. The driver motor is in great shape and runs nicely. $1400.00

pertinent today. Excellent for any engine shop
as a training aid or if you just want to know how
things are done.  $15.00 ea.
