Blob, I too sometimes get confused by the strange language used by our friends over the pond! When I visit Texas I am baffled as to why they call the ROAD the PAVEMENT, even though it is not PAVED with PAVING stones. Then they call the PAVEMENT the SIDEWALK, even though no-one ever walks on it because they are driving their GAS (!) -powered AUTOMOBILES on the PAVEMENT ! Sorry, Jim, could not resist!
I have seen other IFAs in "Chitty chitty Bang Bang", the newsletter of the USSR (Unloved Soviet and Socialist Register), I think one or two of their models were based on DKW/Auto Union/NSU
