I just bought some air force pen clips from wood pen pro, they were nice heavy built clips, made for European kits in chrome finish. A little pricey but customer was happy with them.
Wood pen pro was who I was thinking of but after looking at his site I don't think what he has is what my client is looking for. I'll show him the site when I meet with him this weekend. After doing a search here on IAP, the links listed in previous threads can't be found.
