There are some photos of gas turbines at, http://www.alanjstepney.free-online.co.uk in the Guildford section and also in the Bristol Section, showing gas turbine engines and in the Guildford section, a couple of gas turbine locomotives. In both cases, the models and exhibitors are members of the Gas Turbine Builders Association. I understand that the association has a lot of information available. The only contact info I have is a phone number, (0)2074 957 585. alan@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx www.alanstepney.info Model Engineering, Steam Engine, and Railway technical pages.
