Great pictures Arunas.
If the numberplate is to be believed this is dated at 1949 which makes it a pre-production car. I'm unsure if this was a proposal for the Paramount styling or merely a one-off built by a seperate firm, but the date encourages me to believe the former.
I'll move it to solved, but can anyone else shed some more light on this car? (I know you probably just want to stop looking at it now!)
