Here's one for the die hard trooper experts:

How many tube stripes are there on a trooper helmet? I for one can't figure it out. Even the right and left side on a trooper lid have different numbers of stripes.....





Sometimes there isn't any striping at all....

There's only three numbers....11, 14 and I forget the other one...either 12 or 13. Ya they can vary side-to-side.

The ones without any were early helmets....I'm just guessing on that.
