Regret I do not have a photograph of 5185 HA in my collection but I took the attached picture at The Transport Museum, Wythall (just south of Birmingham) on 16 July 2017. It shows their LS18 fleet no 5212 (5212HA) which is similar in many ways to your excellent find. It has a Leopard PSU3/4R chassis, Leyland O600 engine and 4 speed air operated semi-auto gearbox. It entered service in 12/62 with a Willowbrook body with B53F layout and bus seats.DickyOB wrote: ↑02:21 Thursday 4th January 2018My girlfriend found this gem for me, a picture of 5185 HA brand new with the black roof, as you mentioned Adam. I told you she was special… http://www.classictransportpictures.co. ... 56373.html
Next along is Midland Red built S21 fleet no. 5868 (JHA 868E) a chassisless semi-coach new in 07/67 with their own 10.5 litre engine, 4 speed Self-Changing Gears semi-auto gearbox and DP49F layout and dual purpose seats.
Fleet no. 6145 (SHA 645G) the Plaxton C36F bodied Leyland Leopard coach next in line has a PSU4/4R chassis with O680 engine and 5 speed pneumocyclic gearbox and was used mainly for coach cruise work in its early life.
Finally Midland Red built S17 fleet no. 5767 (EHA 767D) is a chassisless service bus new in 09/66 with their own 10.5 litre engine, 4 speed Self Changing Gears semi-auto gearbox and B52F layout with bus seats.
If you have a day spare the Museum is worth a visit, especially on event days when many vintage buses are on the road working services in and around the local area. For a preview they have an excellent website with connections to Facebook which has news of all the ongoing projects.
