Peco N Scale Rule.

I hadn't realised that Peco supplied such a thing.

I've just noticed it in Squires Tools & Materials Catalogue page 57 at £3.99.
It includes a standard coupling height for Peco stock too.

Apart from being a regular and very satisfied customer of Squires, I have no connection with Squires or Peco.
There may be other suppliers.

I have one of these and very useful it is too, especially I find when making buildings as in my minds eye I always imagining the models needing to be bigger than what they actually are. I made a mock up of my house once and was astonished as to how small it is against a wagon.
