My SCWPM shows even more to the story. It has the note listed as P31 (ND 1987) printed by TDLR, then as P31A (ND 1991-2) printed by BABN, then as P31B (ND 1995) printed by FCO, then as P31C (ND 1996) by TDLR, then lastly as P31D (ND 1997) by BABN. There are many modern French area notes that were first printed by BdF and then subsequently by FCO. I have always assumed this was just a matter of purchasing contracts and pricing, where one printer has the contract for a couple years, but when the next contract is put out, a different bidder wins it.
