While Dicho has this going, and in the event a German memorabilia expert chimes in...
My Dad has a Nazi flag that belonged to my Grandfather. He (also a veteran), got it from a neighbor who was in the 82nd AB. Now this flag is solid red, high-quality linen, about 5 feet X 4 feet, and has a small green felt rectangle in the upper corner closest to the grommets. On the felt are two numbers that are embroidered in. I'm assuming these are probably unit designations. The swastika is on an off-white field that's probably 2 feet in diameter, and sown on both sides to the red field. We want to frame it and donate it to a museum, but I was curious as to whether or not there are resources where I could find out what the numbers on the green felt patch designate?
