Nikon do not provide information on manufacture dates for either Nikon bodies or lenses. I do not know any web sources for body serial numbers but Roland Vink's site is useful for estimating the manufacture date of Nikon lenses http://www.photosynthesis.co.nz/nikon/serialno.html
Photography is a bit like archery. A technically better camera, lens or arrow may not hit the target as often as it could if the photographer or archer does not practice enough.

For estimation purposes, the sale receipt would be the best clue. Nikon's such as the D3s, D700, and D300s sell about as fast as the stores get them in stock, and obviously the distributor is moving them through quickly after arriving in-country(evidenced by the frequent backorder or stock churning). A sales receipt might lag by more time only prior to new release. The D90 or example and the, at the time, new 18-105vr lens must have been in production for a while before stores got them. That is likely the reason many people had a contact oxidation problem with early production units, they were sitting in a warehouse for months before actual use. Use is what keep electrical contacts free from oxide caused high resistance connections. Items like the D3s was in short supply the day it was released and demand outstrips the production capacity of the factory so the time between manufacture and new owner's first click is a couple weeks.
It would be interesting to see what goodies are already stacking up in warehouses at the factory that will be announced later this summer. Stan St Petersburg Russia
