This is the date code of my 300mm 2.8 L non is... anybody care to hazard what the second letter is meant to be? Wiki says these lenses were produced between 87 and 98...a "chipped" F would make sense, but am I missing somethingg?

Looks more to me like a straight up 'I', which would be 1994. If it is an 'F', then it's 1991. Both letters fit in the range of production years.

We need examples from adjacent years, is the printer separating the letters and numbers?

If so, it's an I. If not, it's more likely an F.

Thanks folks. Figured F or I really were the only choices but wanted second opinions.

Seems to be an I. I would of thought there would be less space between the I and the #. I guess I was wrong.
