I have visited the 7A of Olivier de Serres. 

It is without doubt a 7A preseries since it has the streight gear lever and the contrary gear . The engine has the outlet exhaust of the second series.The car is slightly rusted but complet and the body is without bumps. 

At the present date (April 2008) this 7A, Mr Gauber and CITROEN Collection 7A are the only preseries known. This 7A is black/black coloured.
