Rotring 600 Ballpoint Pen (Black, Knurled Grip, Ink Color Indicator, Parker)

Description

For sale is a black Rotring 600 old style ballpoint pen.  It features a knurled grip and a rotating ink color indicator.  The pen was used lightly and has no more than micro/very light signs of use.  The 600 has a metal construction.  My understanding is that all these older 600s were made in Germany.   The pen measures just under 5 and 1/2 inches long and weighs 26g with a refill inside.  It takes the common Parker-style refill.  The point is advanced and retracted via a push mechanism.  The pen will come with a Schmidt blue ink ballpoint refill installed.  No box/papers.  The pen rest in the pictures is also not included.  I will ship the pen via insured First Class Mail.  Thank you.
