In the De Angelis,Henry &Francis book [ Model A as Henry Built It] they give 3,429 76B's in 1930 & 2,637 in 1931. This was US production. Ford Canada also sold them as many were shipped to New Zealand, India, Sth Africa & Malaya but all up probably only around 1000 & some would have been 76A's sold in 1930.
Im sure there are other sources for production numbers of body styles.
