Neil, i have experimented with all kinds of pen styles over the years but i can't seem to sell anything other than a done up slimline .. At my last works the director asked me if i would make a couple of pens for some customers who was going to be visiting the factory .. He asked me to show him some examples of high end pens, to which i did .. He then asked me what the price would be, the pens were Statesman fountain pens and i stated that he would be looking at £50, and that i was giving them away at this price. I ended up making a couple of Barons that he paid me £20 each for ... The company had made £170+ million that year ... 
So on my patch it is Slimlines mainly and Barons for my high end pens ..
