The Parker 75 is a mid-twentieth century modernist classic. In fact I wrote the first draft of my doctoral dissertation with one. These pens are smallish, light for a silver pen, and remarkably well balanced. 

I wrote the first draft of my doctoral dissertation with one, so I know you can easily write all day with one, because I have.

This is a very fine example of an early flat top pen, complete and correct. The nib is a #65 Fine and the pen has the correct early convertor. The blacking between the chisel cuts has faded , but on request I can easily restore it. No dents, no dings, no chips. (DS23)
