Further to James's pictures of this along the 479 route, here are a couple more of ACZ 590 at Bluewater, on 24th September, which (unlike its five sisters with Autocar, including ACZ
690) is definitely licensed to Brookline. It looks as if between us we will have to keep an eye on the Autocar & Brookline fleets to pick up any buses that are transferred between the two fleets, given that the purple livery now seems to be common to both. Note also the retention of the centre door, and the use of an LT-style non-digital destination display on this and at least some of the Autocar examples. It would seem the Brookline version of the new fleetname has not yet materialised, unless of course anyone knows otherwise.
