The Black cat brand was ( im sure it was 26/26A/26C/36/36A/36C), different service numbers for the different variations on north side, then service 39 got extended from Sunderland to Pennywell, and service 26 only went from Sunderland to Heworth and service 36A and 36C did the circular routes around north estates.
