05-06 line prophet size question

this question will most likely be best answered by someone who owns the same skis, model year and all

so i got these skis, the green ones, a few years ago in april of 05, 6 months before they came out (this may be important later).  anyways, recently, while thinking about selling them, i noticed "180" printed on the skis on the ball the bird is holding in the crest......... but these skis have only ever been made in 186 cm, as far as i know.  i tried measuring, but i dont know exactly how they measure skis and the total length was right between the two numbers in question, making me even more confused.

my question is, do other people who own these skis have a "180" printed on their skis in this spot in question, or a "186"......... or if someone could measure their 186's using some repeatable method, that would be great.  i just dont want to sell them as 186's and then find out they are actually 180's that were never released and have a mad customer on my hands....... i dont know why they would print "180" as the only noticeable number on a ski that measures 186 cm, so my conclusion is that they are 180 cm, yet a 180 cm prophet 130 was never released.   and i have really good eyes, it really is a "180" not "186"

any help to my question would be greatly appreciated.
