Kevin, the two Ward's you have shown have the two rare backs (as I would have suspected). Even though the lower one looks "regular" he has the Type 3 back I mentioned earlier--see the last line on back vs. a normal E121 and you will see the difference. The sample size of those backs is still pretty small (as they are the rarest of the 3 backs), but what I have documented of them the checklist will look a lot like the "ends in eighty" subset. I would be surpised to find a Ward with a regular Type 1 back.
**Just as a refresher, here are the known back variations at this point (the reversed back isn't a true back variation, just a printing variation)
