This is a kitbash and recolor of the 1:64 AEC Routemaster RM double decker bus edited by Stagecoach Fan (from the original Paper Bus Connection RM?) into the RMA forward door standard length variant double decker bus.

Edit: 2 June 2019
Added recolors:
1) post-BEA service RMA used by London Transport in original orange and white colors before repaint.

2) prototype RM during testing by London Transport in 1959.
