Sheaffer Demonstrator pens from the 1920s and '30s turn up so rarely, this might be your one chance in a lifetime to get this pen. You can see the cut outs made into the barrel of this rare vintage pen. Sheaffer Dealers and pen reps would have these pens to showcase how a Sheaffer pen works on the inside. You can see this pen has been fully restored with a new ink sac. It is great to see this pen working through the filling and recapping cycles. The trim shows a little brassing, and there is some light wear on this pen. You will write a medium line with its 14k gold Lifetime nib. It has an early 1930s inkfeed.
