Dating parker vacumatic pens
When the pen arrived, I was surprised at how different it looked from my father’s.It had an obviously older looking clip with a blue diamond, and for the life of me, I could not unscrew that barrel to fill it! Over the next few months I discovered that this was a Vacumatic filling “51” versus my father’s old Aerometric filling “51”. Months later, I saw a classified ad in an antiques newspaper, advertising old fountain pens for sale.Someone was advertising a restored “51” with a gold-filled cap and burgundy barrel.It was exactly like my father’s, or at least I thought so.
I read all available books, but they provided little help except that aluminum jewels were a feature of the first year “51” pen.
Development of the Parker “51” was completed in 1939, the 51st anniversary of the Parker Pen Company, thus its name.
