Thanks for this. I've long been frustrated by the fact that clips are the one (visible) pen component I haven't successfully made. After reading this, I might have to give it another shot.
One question, though... How well does the nickel silver hold up to pocket-clipping? I'd tried making one out of stainless, and found that it was initially too flexible, and worried that when it work-hardened with use, it would end up too fragile (between the two, it hasn't seen any actual use). Although I think I was also working with thinner stock than you.
edit: Also, how did you form the post on the bronze piece to rivet through the clip? Or is that a bit of bronze rod that goes through both pieces?
