Brian / Rhett - Just want to make sure we're all talking the same language...
Type 4 - is the newly discovered (couple of months ago) reverse were the first line of printing has the tight spacing between the words. Type 1 (normal most common back) on the left and Type 4 (tighter spacing on first line plus in this case reversed) on the right.

What are we calling "reversed" back? Is it just "reversed" or Type 5? I think Brian is refering to it as Type 4 in his last post.
Anyway here's what I can offer:
I have a bunch of Type 2 cards - if you want me to identify them for you just let me know.
I have "Pat" Shea and Aaron Ward in both
Type 2 and
Type 3 in my collection.
Type 4 - tighter printing on first line
Sisler - Throwing (also reversed)
