How big are the chances you find a qualitron ledpen in a case..no not that big.
my first qualitron ledpen (1972)was nos from a friend who had it stored for many years..it was a free gift. the one on the bottom of the first picture.
Then today i got a second one and also almost nos in case (just missing the extra pens to write).
They both still write and work after 40 years..these were the first pens with a watch ever made. It's like the Pulsar p1 for writers
Now i think i have them all..the first, the second (sterling) and the first calculator pen...funny as i normally collect lcd
btw if someone is interested in a qualitron ledpen..just pm me.
