Also, It's very possible that that 16 inch shell isn't green and the picture was colored in incorrectly.
the original was a B&W pic
It could be a blue AP round for bunker busting , and then the tip is just a ballistics cap
They were known to ricochet on dirt and were more solid (which would explain it laying around , not deformed)
Lastly , I think it's a bit small for a 16 inch, or the PFC must have been very tall.
a 16 inch round is 64inches/162 cm long
the shell in this picture is about as long as he is tall, while sitting down.
Surely he's not 64 inches high , when seated???
Average height of a man in those days was about 69 inches They were 4-5 inches taller, while standing
