Early 70s I would think. You had to be cool to have one of these fine sets. We have the yellow/orange T220 with a Wordpicker highlighter. Then we have the Black T220 ball point with a Wordpicker. Last we have a Scripto Thin Line 49 pencil. These use 0.9mm lead. All these are great items to collect but I think you should open them up and use them. The T220 ball point pen has always been one of my favorite pens and refills are easy to fine. Nothing like using a 40 year pen or pencil. Add them all to your collection.
Here we have a very nice walnut desk organizer. It measures 10 1/2" by 6 1/2" and is about a inch deep. I am told from the 70s.
You open the lid and you have a slot for an eraser, below that post-it tabs that are refilled from the back of the case. Then a Rhodia small bloc pad, Post-it notes, a slot for paperclips and at the bottom a slot for a pen. I have placed this Desk Organizer on my desk and it works fine. Add one to your collection.
Her are two new pens in the Supply Room. Top pen is a Conklin Herringbone ball point pen. Most places I have seen this pen for sale it is listed for about $85.00. I bid using ebay and got it for $16.00. The second pen is a Monteverde Regatta in blue and white acrylic. I have seen this pen for $$85.00 and I got it for $22.50. It does pay to shop around. Both use Parker refills so with the different refills available you are sure to find one that works for you. Add them to your collection.
Parker Vector pens have been around for a while and I am sure we have all had a Vector rollerball or a fountain pen at one time or another. This is a some type of rollerball prototype set from around 1986. There is only one pen which has a blue top and blue at the very bottom of the pen yet there are three other caps in red, black and green. Nice set for my collection add one to yours.
