Ed, I received about two-thirds of the parts today. It was mostly Pioneer but a fair bit of other stuff as well. I posted on the Poulan thread to get rid of some of the XXV parts. There were four new cylinders, a 1200A, a P38, a P42 and a P51 jug. There is a P62 piston and a P12 piston but the others were for other makes and have no numbers. There's about twenty .404 rim sprockets, and an ignition for a P50 (a good backup for mine), an electronic coil for a P26E, some mixed air filters (nothing for the small P-series), oil caps, a P40 muffler, starter handles, 20 clutch drums (mostly non-Pioneer), a flywheel, a few gaskets, pulleys and some hardware. I didn't get the screws I was looking for yet. There was a rubber air filter boot, two plastic brake handles, spikes for a P40, and plastic pulley bushings. One thing I was happy about was a bag of bar nuts for the big P-series, the ones with the shoulder on them. Another thing was three brake bands for P-series. They cost $40 new if you can find them.
Overall, I got a heck of a deal on this stuff and I can't wait for the last box to get here. It's over 40 lbs. and has a parts 1074 in it and should have some chains as well. I'll post an update later.
