An old small 12" rare Rabone folding caliper rule which we believe to be an old ironmonger rule.
We believe this to be an old very rare rule.
The side of the rule is marked 'John Rabone & Sons, Manufactas'.
This rule is marked out in inches up to 12", along with lots of different measurement scales / charts which include 'Flat Iron', 'Square Iron', 'Round Iron'.
Condition: brass sliding caliper rule slides, please see photos for condition.
