Yes, Nording does this on this line of pipes, so that if you break or damage a stem, you can reorder another one, by just sending him (or the retailer) the number stamped on the pipe. Very few Nording pipes have a flush transition from shank to stem. Most of his stuff (as other Danish pipemakers also) looks like he just grabbed a random stem and stuck it on his pipes. But, he does have some older pipes from back when he dabbled with making them himself that have a nice transition, but these will cost a pretty penny.
