A WW2 PRODUCED WM20 ENGINE .
ONCE CLEANED YOU WILL FIND AN ALMOST PERFECT MAG PLATFORM, THIS ENGINE HAS SEEN LITTLE USE .THE HOLE FOR MAG SPINDLE SHOWS NO WEAR ,THIS IS UNUSUAL.
PETE GOT THIS RUNNING AND PUT A NEW INLET VALVE , THE OLD ONE HAD SUFFERED MOISTURE DAMAGE .
ALTHOUGH RUSTY THIS IS A £200 HEAD AS ONE AREA OF DAMAGE BUT REALLY THICK FINS ,AGAIN SHOWS NOT A LOT OF RUNNING HOURS .
SAME WITH BARREL -VERY GOOD AROUND EXHAUST PORT .
YOU CAN SEE ITS A GOOD HEAD .
HERE IS THE WORST PART OF POOR STORAGE ! THE DAMP HAS EATEN INTO PISTON TOP , WE RAN IT BUT ITS NOT IDEAL AND SADLY IT WILL NEED A RE BORE .SEE PICS .
A 1944 ENGINE.
A LATE WAR ENGINE 
FROM CONTRACT S5209 – RAN FROM LATE 43 UNTIL JULY 45. I WOULD PUT THIS AS A 44 ENGINE .
