Thanks for the suggestions. I may have mistakenly said REV when I meant VER, or visa versa. I do understand REV G is always REV G, etc, etc.
So is anyone familiar with where does REV 13 or REV13A fall into the order. Are they the very first? There is a REV13B on ebay. How many REV's have there been & what is the order they fall in. Obviously G is before H & so on where do the numbers fall into the order of things.
Yes, Barry must be shaking his head right now.
