The "O" licences were operated by igo which was separated from the other arms of ATG (Group). This is much the same way as HCT do or did operate as I understand it. As a point of interest PD1129 O licence has been in the hands of WMSNT, later ATG (Group) since at least 1990 where 10 discs were awarded in order to operate larger vehicles on registered services in Walsall, Wolverhampton, Birmingham and Coventry. The fact that NatEx has now had to operate all vehicles under "O" licences will put heavy financial restrictions on the services operated, especially Ring and Ride, in the future which will be interesting to observe short to long term. I sincerely hope all goes well with future TfWM funding.
