Einsamer: When my friend built my U-99 model I noted that the center of the flag was missing. I contacted Revell models og Germany and they advised me about the laws and the swastika. I reproduced the flag by going to a copy shop with a color copier and had them reduce down the flag found on page 26 in U-Boats in Action by Squadron Singal publications. I then cut out the color copied flags swastika and applied it to the flag that came with the kit. I then carfully cut clear scotch tape the same size as the flag and appied it to both sides, this helps preserve the decal. It looks really great for a stiff static flag.
