We know that Studebakers were produced exclusively for l/lease which would include Great Britain .
Perhaps the vehicle in question was l/lease and passed on to an ally and may also have been a 6x4 version which were used for transporting supplies and troops in the rear areas.
The nature of it,s work may have involved having the tail gate down hence the holes for the tail lights .

I realise there is a lot of maybe's in the above but there are questions which may not have an answer with out more evidence .
We do know that the truck has timken tandem drive to the rear wheels and a std steel body fitted to a number of makes in that era .
