WP and MT Dryer
That WP dryer is the last of the 2 speed blower models, probably built in 1965-6. Dan didn't the first Power-fin MT agitators still have a replaceable aluminum spline ?, I know they can get stuck but if the agitator comes out without the spline a new one can be installed. The ad for these MTs says the dryer is 1972, it should have the bar style sensor baffles by this time.
