Flak Jacket Lenses Confusion.

[heslop15]

Hi, I bought these as being authentic Flak Jacket lenses in original packaging. The lenses appear fine, as far as I can tell, the confusion is the SKU on the bag is 96-608, which I think is for Flak 2.0 lenses but the lenses themselves, to me, look like Flak 1.0.
Can anyone confirm which lenses they are and any thoughts on the SKU, i.e. are they Flak 1.0 lenses in a Flack 2.0 bag. The sticker on the bag has discoloured with age and looks genuine. Is there any way I can test that the lenses are authentic?
Thanks

Those are flak 1.0 lenses and the packaging looks correct for 1.0, the flak 2.0 were not offered with xlj that is just 1.0. the 2.0 was just called XL. And here is a pick of a 2.0 lenses where they have a grove cut in them to install...
