I´ve read in another thread that the only real silver Sonnets are the Ciselé and the vermeil ones; the Tartans are silver-plated. What about the Fougère? Is it sterling? I´ve seen it for sale for double the price of a Tartan, so I had always thought it was really silver; now I´m not so sure...

Mine has the Parker hallmark and 925 stamped on the cap.

I believe the Sonnet was produced in this finish in both plate and sterling.

Thanks for the replies!
Things got more difficult now - I was thinking about buying one online, but now I´m not sure whether the one I saw was plated or solid silver. I remember reading that (I think it was in the Cross forum) that not all solid silver pens are hallmarked, so it seems I´ll have to believe what the seller says...
