where is the engine serial number?

ok, Ive check, rechecked and rechecked again. It is definitely a 566416 - the prefix U2U stuff is virtually impossible to read but the U2U part is visible. I even checked the hpop and it says 566416 too. Here are a couple of shots. Im not looking at the wrong thing am I?

It still sure looks like a 3 to me!

If I gave you some grey hair.

ah, no sweat. I'd rather be doubly sure than wrong!
