Old Wooden Folding Rule - No. 51 1/2 S (Boxwood) 81 The rear is marked '5/8'An old imperial 24" Wooden Folding Rule No. 51 1 2 S (Boxwood) marked out in inches. The rule is marked 'No. 51 1 2 S, Warranted Boxwood', it is also marked '51 1 2 S' again on the other side. We feel like this is an old Stanley Wooden Rule however we are struggling to find a reference to this model number which either means this is made by an alternative maker or it is super rare. Condition: please see photos for condition.
