It is not a Texas plate, but a French manufacturer's plate (characterized by the W) from the Département 92 (Hauts-de-Seine), where Hrubon was located in Neuilly-sur-Seine.
Well I happily cede to the more informed!
The writing on the plates has Dallas above the actual identification number, and Texas below it, so you can see where I would be led astray... Should've blanked out the numberplate!
Unfortunately my source did not include more than a snippet of information so I had no idea Hrubon was based there, I only had Geubwiller as the location under the Schmitt name.
