Margarette is described in the Harrison Marks movie synopsis of glamour film No.44, ‘Margarette’ (1963) as ‘Continental’. He did three still shoots with her and photographs from them are in Kamera No.52, No.53, No.60 & 61 and Kamera Special No.3. Margarette isn’t continental at all but actually English model Babs Dorne, who appears on this Model Index card under that name with the statistics 36-22-36 and being only 5′ 3″ tall. So overall Babs is a nice little package indeed 🙂
In Femme issue 1 (presumed to be issue 1, as not numbered, June Russell on cover), there is a blonde inside called Margarette Mitchell. Could be the same girl, but hard to be certain either way.
