Hey David,
Tom is one very lucky guy! The Series 00 machines (66-67) were the first of the '06 series, starting in January 1966. All the early 06 machines had the three level water selector - Small, Med, Large, regardless of tub size. Also, the 806 machines had a Wash 'n Wear cycle which was replaced with Perm press starting on later machines (late 67? on). My favorite aspect of these very early 06 machines is the early Powerfin Agitator. It has the 4 normal flexible fins, then the lower set of 4 posted fins. These agitators also have a plastic baffle (2 piece) on the bottom of the agitator just like the previous Bakelite agitators. The 1969 Helical Repair manual has a great outline one the differences between the two piece (early), and one piece (late) agitators.
This agitator also uses a fine mesh for the lint filter, whereas on later machines the filter is a molded one piece unit.
Tom - Congrats on your beauties!
Ben
