Thanks Nutloose, a lot of that stuff looks past it's sell by date. Trouble with acquiring Gnomes is that they are still very much in use and it appears that suicidal Yanks use them on dragsters and power boats. We're hoping to get one on loan from RR but that will be on a stand for exhibition use. If we could just get the exhausts at least we could fit the blanks properly but it's early days and we don't expect the aircraft to start its move until mid July.
Jetenginetrader looks to be a handy outfit but no Gnomes at present.
