I was just following this thread: Parker Sonnets and Noodlers, and thence to this thread: Parker Sonnet hole in cap. This inspired me to check both my genuine (JML - happy customer) and fake Sonnets' caps (it was JML's comment about the rivet holding the cap inner in place).
On the genuine Sonnets, the cap's inner is indeed blind-riveted. On the fakes, the inner is held in place by a nut and bolt!
So, if you have a Sonnet you are a bit suss about, check out the cap.
Maybe this isn't news to anyone, but just in case ...
Didn't help me though: I have another 'Sonnet' which I'm about 90% sure is fake but cannot prove it one way or another (Another fake Sonnet?). The cap inner is riveted on that one too.
Have fun at all times!
