According to the dating system described in Richard Binder's book about Japanese short pens, this pen was manufactured in the Hiratsuka, factory on April 1971.

 

Yes I was curious because I thought the Myus were released in the Fall of 71, around September.  So prior to finding my pen, yours with the 671 date code was the earliest that I had seen.  Finding one with a date code from April 71 was almost inconceivable!

from 1925 waterman catalog. It looks like for an extra charge its possible to get the telescope cap and ring. Im unsure if extending is useful to begin with. pen feels very flimsy when extended and there is a good chance of the top bit falling off. half posting the cap may have been a more solid option compared to this. Im not sure if its just the pen i have though. 

I don't have any evidence for this except intuition as a user, but I suspect that the telescoping cap is not supposed to be used to extend the pen. The telescoping cap only comes in ringtop (none with clips) and it seems to me the use is so that the pen can be quickly and easily detached from its chain/lanyard while still allowing you to post the inner cap for length. This way you get the normal length of the pen style, while not having to keep it attached to the chain in order to write.

its a bit difficult read the line after the pens . it basically states " Telescope Caps offer an added convenience when pens are carries in the pocket, on a chain. The Telescope Cap fits firmly and securely on the cap of the pen yet permitting the pen to be quickly and easily detached for use. see pages 33,34,41,42,49,50."
