I think it would have been no 12 . Yes, he is listed there as a glass bead & button maker in the PO directory of 1855, though George Bradley is there in the 1849 edition. However the Whites directory of 1855 lists Dudley as a baker & glass toy maker at 64 Edgbaston St, with William Dunkley (missprint?) ,baker,at 12 Inge St. You should remember that the dates are publication date, and the results are likely to refer to at least the year before, and this difference may differ between different firm's directory.
Dudley is not mentioned in the 1849 directory, In the 1858 Dix directory he is a glass toy maker, at court 5, Upper Windsor st; with his home at, 2, Coleman st, but by 1862 he has gone
