Yes, there’s a rumor that P8M versions aren’t hot. Plenty hot enough for me to give it away to my watchmaker friend and kiss (not literally) it goodbye. I picked up a meter as a precaution. They say “normal” background is around 0.10 mSv/h and I got 4.5 right up to it….and about .30 mSv/h 2 feet away. The thing is also not airtight. Good with no kids around on a bookshelf but not cool enough for me. Good riddance!

Fascinating thread! Looks like a lot of parts failed in a brittle state. Some of the structural members fractured instead of tearing.

The spiral gear is likely from one of the vertical cross shafts inside the accessory case of the Rolls engine. Might be the driven end for the mag or fuel pump.

The one gauge face looks like a boost gauge. Please be extremely careful as many of these and likely that one (the boost gauges, compass, etc) were painted with radon, which is radioactive. The radiation does go through glass and the dust is very bad if opened. I would recommend borrowing/renting a geiger counter just in case. I had some in my old shop (attached pic) built at that time that glow to this day.
