Psst - Landroger: Belvedere = same engine(s) as Wessie 1 & 3, ie Napier Gazelle. Turboshaft, which I'm pretty sure uses a turbine, no?
Whoops! So memory is probably playing tricks then Thud? I have this memory image of, on probably the only time I saw a Belvedere in the flesh, the clatter of reciprocating radial? Not so at all? Thanks for the pointer though and thanks too to Data-Lynx for the picture and additional info.
So, did anyone ever fly one and were they any good? I believe they were used in Burma?
