XRB 416L was carrying registration JIL 7608 when it was loaned to Mansfield, it was Stagecoach Manchester 271 in Magic Bus blue and white livery.
There was also M740 BSJ a Volvo B6/Alexander Dash from Western Scottish (f/no. 340), and a Dart MPD from Ribble, 702- W702 BFV.
There were some Mercedes minis from Lancaster and (IIRC) Burnley, and at least one Dart SLF from a dealer in plain white ( S783 RNE rings a bell but don't quote me!)
I rooted out an old DVD I have that shows some of the buses. Featured on it are two dealer white Dart SLF/Plaxtons, S310 TMB and W671 TNV.
From other Stagecoach companies were Volvo Olympian/Alexander RL N719 LTN, N720 LTN and N735 LTN (Busways 719/720/735) and S132 AET (Grimsby Cleethorpes 132).
Leyland Olympian/Alexander RL F807 FAO (Lancaster 1007), Volvo Olympian/Northern Counties P829 FEF (Transit 829), Dennis Trident/Alexander ALX400 T371 FUG (Grimsby Cleethorpes 371), Volvo B10M/Northern Counties R755 RPY (Hartlepool 555), Optare Metrorider J805 DWW (Viscount 905), Mercedes 811/Alexander F629 XMS (Hartlepool 329) and Mercedes 709/Alexander K616 UFR, L340 FWO, N726 RDD (Burnley and Pendle 616, Red and White 340 and Gloucester Citybus 726 respectively)... plus M740 BSJ, W702 BFV and JIL 7608 already mentioned.
Not a complete list, but not a bad start!
