Based on the good work by DaveW and contributors to this thread several years ago, I created a spreadsheet as the reference for finishing a set of all front/back combinations. The seventh and final R322 Hank Greenberg arrived from eBay last week, putting me at 100% of variations found by Net54 contributors.

While I feel good about this set being complete, it'd be great to add more confidence. Please check it against your R322s when time allows and add any thoughts or updates.
