I found a 140 in an old bookstore. The bookstore has some history, but not THAT long - around 20+ years. The pen is clearly a NOS in OK condition.
I want to know when was the 140 discontinued. All I can find on the web is how it reached its peak in the 50s and 60s, but no info on when was its productions ceased.
Grateful for any info on this. Thx!
