I think that might be "Salome" in her later (clothed) state.
She was a hill-climb special made by Jan Breyer from Morgan, GN and Austin parts but with no bodywork at all. Post-war she acquired bodywork as much to satisfy the Rules as anything and later took part in VSCC events driven by Freddie Giles. By then the engine was out in the open like the Morgan's, so perhaps this guess is off-target.
