UNUSUAL 4" RABONE BRASS & BOXWOOD ADVERTISING CALIPER RULE

Excellent overall condition with odd extended brass caliper jaw. Stamped 'J. RABONE & SONS MAKERS' on the edge and 'SAMUEL MARSDEN & SON LTD MANCHESTER BOLTS AND NUTS FOR ALL PURPOSES' sandwiched around the brass caliper. Awesome to find tool/hardware-related advertising on a rule. Uncleaned as found.
