Here is a very respectable Waterman's 515 from the late 1940s/early 1950s in very good condition.  No bites, cracks or scratches and the cap closes securely in three-quarters of a turn.  There is a little brassing to the clip and cap band, but on the whole, the pen is eminently presentable.  Cleaned of course and new sac fitted.

I post internationally and always offer combined postage on multiple purchases.  I am a member of the Writing Equipment Society.  Please review my seller feedback and do please see the other pens I have for sale. 

Thank you for your interest.
