Heres some pics of my P7M8. Seems to be the highest serial number from what I have read, seen, and researched. The serial number is: 16-134994 with an AH date code. Could possibly be the highest serial number/last M8 built. I also have a handfull of P7K3s (ranging from early IH date codes through KE date codes) that I will be adding to this thread, even though I don't see any list for them on the first page of this thread.
