There are a bunch of IRs in with Longevity Parralel scans accidentally put into the standard base checklist, however which Parralel. Looking at cardboard connection there are two sets of parallels. Some Base Longevity, and others Longevity Base.

The scans I have investigated so far have no SN, leaving it down to Base Longevity or Longevity Base (I initially thought that maybe the checklist was duplicated under two different names....but no according to CC there is...well this Panini mess). Anybody know what differences to spot between these two?
