Rare John Rabone & Sons Girthing Tape Measure

A rare English timber girthing tape measure in leather case with brass fittings, fold-out handle, and original 66-foot cloth (woven linen) tape, made by John Rabone & Sons of Birmingham.  Measuring 4-3/4” across, the tape likely dates from 1940-1960.  A unique gift for the craftsman, woodworker, or any lover of old tools.

Girthing tapes are used in forestry to measure the diameter (girth) of trees and how much lumber they expect to yield.  A tree’s girth is measured at a height of 4-1/2 feet, and when multiplied by length (of a felled log, for example) provides an estimate of the cubic feet of wood.  The gradations on the tape convert a circumference measurement into the corresponding diameter.

This is a well-used tool, with wear and overall patina befitting its age.  Note: the first 20 inches or so of tape is a replacement and was stitched to the original by an owner clearly intent on preserving his investment!  Leather case is marked “JOHN RABONE & SONS – BIRMINGHAM ENGLAND” on one side and “RABONE’S METALLIC TAPE” on the other.  

John Rabone & Sons were a pre-eminent British manufacturer of rules and measuring devices, with origins dating back to the late 1700s.  The company operated as a family business until it merged with Chesterman & Co of Sheffield in 1963.

Dimensions: 4-3/4” x 4-3/4” x 1-1/2”
Condition Notes: Leather case shows dents, abrasions, and overall wear consistent with age and use.  Fold-out handle works well and tape winds in and out smoothly, though not without some slight movement in the central spool.  (We have not unwound the entire tape.)  Tape was repaired at some point and the first 20 inches is a replacement (of some age) stitched to the original.  See photos for more detail or contact shop with questions.
