Breyer is trying to recreate its woodgrain pattern. Aside from two SM keychains from BreyerFest a few years ago, this is the first model to be produced since the 1960s.

The woodgraining is not as good as it was in the 1950s and 1960s, but my understanding is that the process is very difficult and that those who knew how to do it are either too old to do so or have passed away.
