Established in 1906, Frank Moore soon became well known amongst discerning tradespeople for the quality & accuracy of his tools. The Company was acquired by John Shaw & Son in 1945 & James Neill & Co in 1970. Currently part of the Bower Meteorology UK Group, they still produce superb tools & measuring instruments in Sheffield. The subject item is made from high-grade carbon silver tool steel with the patented 'Firm Lock' joint, that identifies the maker as Moore & Wright.A tool used for external measurement of items made by a maker who patented the "firm lock" jointing system now used on many different types of tools in many different industries. These items are now collectible and quite rare as a result are sought by tool collectors in the USA and UK.‘Firm Joint’ external measuring calipers believed made by Moore & Wright.

Calipers like these were commonly used in the 19th and early 20th centuries for precision measuring tasks, particularly in blacksmithing, metalworking, and carpentry. Their adjustable design allowed craftsmen to accurately check external dimensions of objects such as wheels, barrels, or machined parts. These outside callipers would have been especially useful for ensuring uniformity in metal or wooden components, a crucial aspect of engineering, manufacturing, and blacksmithing practices before the widespread use of digital measuring tools.The item is a pair of large iron dividers or outside callipers, used for measuring external dimensions or transferring measurements in metalworking, woodworking, or blacksmithing. The tool consists of: Two curved arms forming a symmetrical, oval-like shape when opened. A pivot joint at the top, allowing the arms to move freely for adjusting the measurement range. A flat adjustment screw mechanism, which helps in finely tuning and locking the calipers in place. The metal surface is darkened and rusted, indicating significant age and long-term use.farm equipment, callipers, measure
