please help, need lot# check on norma hellas deca

[poin]

hey guys,

i just received 25 norma hellas deca today, the only problem is that there are three different types of lot# and ex on them

ten of them have EX7 03
12605

5 of them LT 12720
EX10/03

5 of them EX7/03
LT12606

are these lot numbers legit or what, everything else matches that it is legit except that

If they all look the same they are legit, Norma factories are not really consistent with their stamping of dates and lot#.
I currently have lot 12601,12602 and 12605
