T10 M-1 main case assembly date

[joephil]

I saw a T10 M-1 with "SHELBY GT 350" stamping. Is this an original stamping? (I rather only saw the assembly date stamped on other t10 m-1).
Then on the one dated December 3, 1964 the date is in the opposite direction to that dated February 12, 1965.
Do you think this 1964 t10 m-1 is correct? Is it unique to the early ones?
Thank you

I have personally never seen that before. My cars T10 hadn't got it and it's original.
Could be done by owner? Is it a early 65 thing?

Cheers

My early car has it and the FoRD serial number. Never seen on another car.
