On mine, only the first few near the bowl were marked and some of those were overlapping. The same way near the stern as well. There is no molded stern torpedo area, I had to modify the hull on mine. You need to pin the rudders and the bowl hydroplanes because the will break loose from the smooth shaft. A lot of things are not marked. However, the Type VIIC varied greately in it's production run during WWII. But let's be straight, it will turn out to be a great looking U-Boat. Bob Dimmack (OTW) did a great job, he just didn't make it easy. I had to drill and file all those #### holes, well over 400 (I quit counting).... It just took me about a year to complete the hull and the brass tower (All brass and no fillers, and not the resin one either). I guess that's not too bad for an amature....
