Pre-Worboys level crossing

[ikcdab]

So I am a railway modeller and I have just been building a level crossing with gates on my railway which is set in the mid 1960s.
The crossing is controlled by an adjacent signalbox.
In this Pre-Worboys situation, what road signage do I need to provide. Is it just the old level crossing sign, or is there more?
