I just went thru the list and every card he as well as every card I need was a 1925 issue.
A while back I got a lot that was close to the legendary one and it was mainly 1926 but had a few of what I though were 1925's, the colors were all the same on all of them, I just checked my list of them and they are the ones no one has every seen a 1926 of.
Looking through my notes I show one set selling in 2007 in a oldjudge auction and I just looked at the pics and they show the 1926 with box and the do appear to have a different tint than the 1925 set that was sold in the same auction. Link-

I am going to check the tints on the 1925s I have that are the in missing 1926 to see if any are a different tint.
Interesting stuff.
Ok just adding pics from the auction on top of each other, they clearly look to have a different tint-
