I am back.
This is a difficult one. The name I wanted was Fokker B2. The term Fokker sesquiplane applies to a number of Fokker aircraft, including the Fokker B2, as well as its close relative, the B1, However as far as I can see the photo that strega has included with his guess is, I am sure, the Fokker B2.
Nevertheless, I feel that I must award this to chazchaz, as he came up with the correct name. Sorry if that seems harsh strega, but as Sinco was pointing out, dig a little deeper, and you will find the answer.
So over to you chazchaz, and thanks for your guidance Sinco in my absence.
But well done to you both
