Ross,
It is not clear whether you can handle and inspect the binocular before purchasing. But if so, it will be easy to learn the answers to your questions.
If it's an FL, "Victory FL" will be stamped on the rubber, on top of the binocular. On a small metal plate underneath, near the hinge, will appear "8x32 T* FL".
On this metal plate, there will be a curving arc above the number 32, if the binocular has the Lotutec coatings.
Sorry, but I don't know the Serial numbers of the first FL, nor the first Lotutec FL. Zeiss would answer that question, I know they have answered similar SN questions for forum members. For what it's worth, my Lotutec FL is SN 3236324, so if the one you are considering is after that, it is, too.
