A lot of skipped/missing model numbers - that's a lot of lenses folks! The question is when will they get filled? I went few years back and there are few missing number here and there (for example #2169).
You can check the lens model number by changing the 4 digits in this URL: http://www.nikonusa.com/Find-Your-Nikon/Product/Camera-Lenses/2192/NikonRumors_is_great.html (the last part of the URL doesn't really matter - it's used for the product name).
