Transitional specifications require more caution, not less

Factories do not always change every specification on the same day. During a transition, combinations may appear that do not perfectly match simplified catalogues or online guides.

Before declaring a component “wrong”, look for documented examples close in period and market, and consider what parts were actually available to the factory at that time.

Transitional configurations can be interesting, but they are also an area where overly precise stories are easily built from limited evidence.

The more unusual the configuration, the stronger the documentation should be.
