An old rare 3-fold folding wooden rule (Boxwood) with sliding brass caliper rule.
This old wooden rule has lots of different measurements.
We believe this old rule is marked with the makers mark 'W Marples & Sons', the first name isn't clear but appears to be '.....les & Sons', it also says 'Warranted' and 'Best Box?'.
Condition: all parts move freely, please see photos for condition.
