If there is no Parker imprint around the end cap and the pen has two jewels, it can be dated most likely between 1942 and 1946. The Parker 51 fountain pen is a classic writing instrument first put into production in 1941, when the company celebrated its 51st anniversary in business.
How can you tell a Parker 51?
The imprint on the majority of these pens is at the end of the barrel, near the decorative “jewel”, all in one line. They may or may not have a “1” datecode after the imprint. Some collectors speculate that the ones without a datecode are really pre-production models from 1940.

Can I use a fountain pen as a dip pen?
No. As there is no place for the fountain pen tip to hold a reservoir of ink through dipping. A dip pen has a slight concave curvature. This curvature helps to hold, with the help of the surface tension of the ink, a small supply of ink on the backside of the nib.
Why are fountain pens so expensive?
One reason for this is that they simply have more material, so they cost more to manufacturer. Larger pens need larger nibs to keep the overall look balanced, but some people do say that larger nibs feel nicer to write with. The larger Montblanc 149 (left) has a much larger nib than the smaller Pelikan M200 (right).
How do you store a fountain pen when not in use?
