UNUSUAL CA 1900 ADVERTISING ARCH JOINT BOXWOOD FOLDING RULE

Very unusual scales likely making this a special order rule. One side is standard, the other has 1/8", 1/4", 1/2" and 3/4" scales. Pre 1910 type arch joint and edge scales. All 3 pins present though one is short. No maker's mark, but likely a Stanley. Advertising text reads, 'COMPLIMENTS OF RICKETSON & SCHWARZ MILWAUKEE'. They were a building supply company. Uncleaned as found.
