Looking for aircraft price information

[Sami]

I am updating the AWS aircraft database a bit and checking the data in it. I am especially in the need of reliable aircraft list price information from early (<2000) models. As you may know manufacturers do not disclose the pricing details very much and many of the prices in AWS too are guesstimates based on the aircraft type and size; but I am now trying to make the data a bit more accurate (which in turn also helps the little airlines, as prices of the smaller planes are a bit off at the moment).

I have scouted the 2004 Jane's, and checked the usual internet sources but I would still need some more information to back up the results. (so please don't paste links to Wikipedia or that usual Boeing's aircraft list prices page..   ..only looking for data on older / rare models)

So if you have access to Jane's books or similar resources please PM me in case you have some extra time and can dig up some data for me.
