This model is Ed. 43 Nr. 12 in the Michael Schumacher Collection.  There are 3 variations of this model.  This one is with a white #5.  This is the same model as the Ed. 43 Nr. 11 GP San Marino at Imola.  This model was sold at the 1995 GP Hockenheim because the correct B194 GP Hockenheim car was not ready in time.

This is the second variation with a blue #5.  This model is actually from the GP Germany at Hockenheim as indicated.  This version is without the Vaporetto logo on the mid wing.

These two photos highlight the differences between the color of the #5 on Schumacher's car.
