Sad to say guys but this numbers dont indicate what is in the bag

I got curious after saskia's post so I ordered a few from ebay...

here is what I got:

blue knight 16711 0843 (001179) and 15911 0784 (002480)

dragon knight 17411 0784 (003967) and 17411 0784 (003970)

zorro 17411 0783(005192)

executioner 16411 0695 (003695)

grim reaper 17411 0783 (001940)

snow queen 140011 0465 (001812)

fairy 13011 0784 (000549)

witch 13011 0784 (001602)

Now in some cases you'll notice that the first 5-digit numbers and the second 4-digit numbers are the same... so that could indicate they come from the same box... the second number, the one I've placed in the brackets, could indicate the klicky production number, but not for each of the same klickies but rather the ones in the box,... in the case the dragon knight 17411 0784 must be an indication of the box from which the two bags came... and those bags were numbered 003967 and 003970 ....the other three bags in between contained something else...

But that is not the case with the zorro and the grim reaper klickies... if each box has 48 bags and these two come form the same box, the second number in the brackets must indicate something else... But if we look the fairy and witch numbers there is something fishy there too

I am horrible with numbers but it seems we are back in square one... Oh and my zorro was missing a spur...so who is to say that other little pieces wont be missing from the other bags.. so how can we be sure about the weight measuring
