"Gouby disagrees that two of his three 1889 proofs, were in fact proofs - not sure whether 129's or not, as Gouby has his own unique method of classification, and no Freeman equivalent is given on those pages. "
Gouby always shows the Freeman number if appropriate in his books - page VP19 of his Victorian Penny book lists both BP1889P/F127A (specimen) and BP1889R/F129 (proof).
