I’m seeing specimens out there with “0.5” notation next to the retraction pushbutton, but then I also see others without the 0.5.
At first, I figured this was simply because the text was worn off on well-used pieces, but now I’m starting to think rOtring released versions with and without the notation.
Anyone else have insight here?
Here is some information I found on the rOtring Museum History page: https://rotringmuseum.com/history.php
• The Metallic Double Push is first seen in 1985 catalog (silver 0.5mm) with silver ring and red letters ‘rotring’ near ring.
• In 1987 was available in silver, blue, black and red. The ring and the letters for all colors except silver were silver. The silver one remained with red letters.
• In 1990 0.7mm was available in silver, blue, black and red. The ring changed to red and no rotring letters on body except size near push bottom.
• In 1992 the Metallic Double Push is replaced by 400 series
• In 1996. 400 series is then replaced by ESPRIT.
I ran across this information while trying to date this pencil:
Based on the information above I am assuming that the my specimen is from somewhere between 1990-1992.
