 At the beginning of 1949 contracts were in hand to provide trolleybuses for the systems at Newcastle, Teesside, Wolverhampton, Maidstone, South Shields, Glasgow, Reading, and Ipswich in Britain, Durban, Johannesburg, and Pretoria in South Africa, Coimbra in Portugal, and Adelaide, Brisbane and Perth in Australia.Production moved from Moorfield to new-built extensions at the Guy works during 1954.The first Sunbeam trolleybuses to be built at Guy's Fallings Park site were a batch for Penang, followed by a batch for Hull but by the end of 1956 it was clear that local and international demand for trolleybuses was declining.
