Dr. Drew: Thankyou for that.

So...the way I'm reading your summary, American 7 1/2s are actually British 7s? That doesn't sound right. It is good to know that 7s are 2.4 mm, 7 1/2s are 2.3mm, and 8s are 2.2mm.

Also, American 5s are British 4s(?) and our 6s are Brit 5? No wonder I'm confused.

Let's see, according Eley, 6s are 2.6mm and 5s are 2.8? Huh...
