What is really weird - at least to me - is how old stuff and new stuff can be mixed *within* the same Traveller book, without either clearly enjoying precedence.

For example, during a recent stop at a local used book emporium, I came across Book 1 of T4 for sale for $7.00. So - of course - I bought it. The section on vehicles has boxed text that describes three different grades of grav vehicle . . . but none of these entries include complete game stats (perfomance, cost, volume occupied, etc) and all of the new pictures are identified using the CT names . . . with the CT description/stat blocks right there, unmodified from then-generation-old printings.
