Thanks Carnut, the picture corresponds to a Mobile Shop built on a AVIA (Spanish AVIA, no more active now part of NISSAN) of the 3500 series bodied by MISAR at the end of th '70s or earlier '80s. Now Misar build armored trucks to the transport of cash or other values. Still it's possible to see some of these trucks at work in the street markets in the Catalonia area.
