The Avian in the photo is Mk.IIIA c/n 148.The engine fitted was Cirrus II No.421. It was issued with UK CofA No.1461 on 21.06.28 to M.A.Northrop, and exported to USA where it was registered NC392. The film star posing with it was Lya DePutti. In Jan.1929 it was sold to Russel Simpson, Hollywood, and again in Oct.1930 to W.W.Mayes.
The last record I have for this a/c was in 1936 when it was owned by Jane C.Goodall, Andover (CA?) Hope this answers you question.

George – many thanks indeed, and welcome to the forum.

I should have perhaps thought of dropping a line to the Avro Heritage Centre, but thanks for such a comprehensive answer.
