WASP (William A. Sheaffer Pen) is the second tier Sheaffer. You wouldn't know this if you compared it to new fountain pens. What I found interesting is that it isn't a Medium nib. It is a very nice Fine nib that writes Extra Fine in reverse writing (as the nib says, writes in two ways). This pen has been restored to look and feel like a brand new pen. I am very happy with this purchase.
