Historical unit numbers based on headcode

[flygrip]

A rookie question - Is there any way that you can find out the train unit numbers (e.g. 158850) for a given headcode & date in the past?

The date I'm looking at is more than 12 months old.

Many thanks for your help in advance.

There are no ways to use the Headcode to directly decipher the train number. I suggest you post some details which you know and the other forum members can try and use their sources.
