I have what appears to be a Waterman Thorobred. It has no model marking, although both the imprint and nib note manufacture in England. Although it looks like every Thorobred I've seen pictures of, mid-30's plain black celluloid, lower level feel to it, all the others note that it's USA made, possibly successors to Model 3's and predecessors to Stalwarts. So, is this guy a British Thorobred or some other contemporaneous model?
Thanks!
