Not a museum quality model but nice all the same. I wonder why they chose a short lived WW2 production bus, and not a Midland Red home grown' one? Midland Red were famously known for their own products
The model represents 2583 HHA 60, a Guy Arab II, built by Park Royal in 1944. Birmingham, Coventry and Wolverhampton Corporations had similar vehicle all with wooden slatted seats when delivered. Not comfortable I can assure you and BCT, being ware of the high standards given to and expected by their citizens soon got rid of their buses. Conventional seating was fitted during 1945 - 1947. This bus operated from Sutton Coldfield garage.
The Midland Red ones were re-bodied in 1951 which gave then another four to five years life with Midland Red.
