One case in point is the A side of Victor 16108: the comic monologue called variously 'Limburger cheese' or latterly 'The boy and the cheese'. It was first recorded by George Broderick in the summer of 1900 and released on Consolidated A-7. This was a 7 inch record. In July 1901 Burt Shepard recorded it for both 7 inch and the new 10 inch record sizes, and they were released as Victor A-7, and Monarch B-7, respectively. On 22 July 1904, he remade what by now was called 'The boy and the cheese' on 7 inch matrix A.1647 and 10 inch matrix B.1647. The single-face editions of these new recordings still retained Victor catalogue number 7. My copy of 16108 has '16108A' stamped at the 6 o'clock position, '7' stamped at the 12 o'clock position.
The other side is where it gets interesting. Although the listings of data for 16108-B show matrix B.1646, either take 1 from 22 July 1904 or take 3 from 26 July 1904 as being used for issue, my copy has what must be the take 1 (no take digit written in the dead wax at the 9 o'clock position) of pre-matrix series Monarch 1704, as that number is handwritten (not stamped) in the dead wax at the 12 o'clock position.

'16108B' is stamped into it at the 6 o'clock position however. The recording date shown for Monarch (B) 1704 is 18th October 1902.
