Help Me Know A "51" Desk Pen

[corgicoupe]

Lying next to an Esterbrook 8ball holder was this lonely Parker "51" desk pen sans holder, so I added it to the purchase. It added a mere $5 to the total. It has a date code of 8 with no dots, the aerometric sac shield is matte finish, and on it is written "To fill press ribbed bar...use dry writing super chrome ink...". What have I got?

 

Should I look for a holder? Or just get a cap?

Get a desk base.

...and a cap too.

Decisions...decisions. where to look? Was it a decent purchase?

For $5 you did good.

[FarmBoy]

Most desk bases sell for less than a good cap.

You did extremely good. Buy a desk base for the pen as advised by FB.

The desk base and the shipping will probably be about the same. I have a 51 desk pen just about the same as the one you bought. It came with a desk base, some fifteen years ago. I like desk pens and sometimes ink a 51 desk pen, sometimes a Sheaffer Imperial or Snorkel.
