Welcome to- The Fountain Pen Community!

I am in need of a black cap for an end of production (ca '42 or 43).  Waterman 
100 year pen.  If I understand correctly, the last  year of production, the term 
hundred  year pen was not found on the pen. I have two pens that are identical 
except for one detail. The nib on one states Hundred Year Pen and the second is 
an Ideal nib. The reason I need a cap, is one has a missing clip, and from what 
I have been told, these clips are riveted into the cap. 

Thanks, Randy
