Hi there,
nice find! This vid may interest you:
http://www.youtube.com/watch?v=cVDxb1laQaYThis is an ex - Wehrmacht Eilbulldog with the typical configuration (exhaust, rear wheels, no winch, no Cabrio hood). This particular example was sourced out of Scandinavia as well! I have seen it in person (the one in the vid) and it is very nicely preserved. I believe this is a good guideline how your Bulldog did look like.
Being a 1941 modelyear it is most likely this was a military ordered Bulldog from the start and not a seized former privately owned one.
