Question on a 1971-S DDO FS-101 proof penny

TequilaDave

So I found a nice 1971-S DDO FS-101 in a proof set this weekend and was doing a little research on it and am getting a little confused. My find is clearly a stage B specimen and shows all the right die characteristics for a stage B. While doing a little research into previous sales of this coin, I came upon this example that HA sold with a label that doesn't correspond with anything PCGS currently offers and I'm wondering if a T-2 was onced used to designate a "stage b" or is this simply an old label and this variety FS-101 and 032 have been combined?

Probably. May need to look at a current and previous CPG to verify, though.
