I think “SPRIN” is pretty clear, once you have an idea what to look for. I’m not trying to be wright here, and still I could be wrong. In fact, I thought it was a NARROW seat at first glance. However, that first letter is definitely not an “N” and I believe this is a “SPRINTER “ saddle. Only my opinion. Anthony
Oh I know, that saddle is the first on the list but when you scroll down you see the Sprinter. Looks like you found one though, yes they are not cheap. Would love to see some pics of your old racers. As you know I have a couple as well, IJ.
