Can you identify this model vintage Waterman Fountain Pen ?

Dear Colleagues,

 

Can you identify this model of vintage Waterman fountain pen ? ( pictures below )

1) Also, is this vintage nib smooth and is the flow likely to be good?

2) Is the size 2 stamped on the nib equivalent to a fine or medium nib?.

 

Thank you

My Google-fu says it is a Ligne 60 and, given the number 2 nib, the "Lady" size pen. The Men's version was a number 3 nib.  The nib number will not tell you line width.  That might be stamped onto the underside of the feed.  
 

It's a visually fun looking nib with the half-way stamped keyhole but neither potential smoothness nor flow rate are readily discernible by me.  If you are contemplating a purchase ask for a writing sample.
