Mike,
Nope, no Jagdschein. I could have gotten a temporary Jagdschein, good for a week or so, but I only had one opportunity to hunt in Germany, and that was with a friend who was a forestry student. He assured me that as long as he was with me, everything would be OK.
At the time I was still a captain USMCR and a former member of various service shooting teams, which may have had some effect on the situation.
We were in such close proximity to France that the store manager was used to selling firearms to French customers who would then take them with them back to France. I never knew whether it was legitimately or illegitimately. I guess I fell under the same category as they did, in the eyes of the dealer.
