How to identify pen?

[bala nemate]

Hi All,

i have used fountain pen and i want to know it's background - name, price and so on. is there specific sites dedicated to pens?
it is black and gold S.T. Dupont. On piece that purpose is to hold pen to paper etc (i do not how it is called in English :) ) is written "made in france 5J04 F 83". On nib - "D / 18K / 750 / M" (in rows)
I tried to google with these parameters but no results...
