Perhaps one of you gents can help me out here and clarify...

Would this Barnton cap be essentially the same as an "Ivy" cap?

I'm trying to learn all the differences and I'd like to get the "Barnton cap" in USMC Leatherneck tartan. I'm sure I'll order it anyways but I'm just trying to learn if "Ivy" and "Barnton" are all the same thing!
