THE INFORMATION AVAILABLE ON THEODORE DUVAL IS LIMITED. HE FIRST APPEARED IN THE HARTFORD CITY DIRECTORY IN 1867 AS A JOINER. HE WAS GRANTED PATENT NO. 97,177 ON NOV. 23, 1869, FOR THE ADJUSTABLE DADO PLANE SHOWN IN PTAMPIA VOL. 1, PAGE 124. THE TOE OF THIS PLANE IS STAMPED " HARTFORD PLANE CO., PAT. NOV. 1869 ", HOWEVER A THOROUGH SEARCH OF HARTFORD DIRECTORIES FAILED TO REVEAL ANY COMPANY WITH THAT NAME. AN INTERESTING FACT IS THAT DUVAL'S PATENT SPECIFICATIONS IS ONE OF THE VERY FEW PLANE PATENTS KNOWN THAT WAS SIGNED WITH AN X ( HIS MARK ), PERHAPS DUVAL COULD NOT READ OR WRITE. PLANE IS IN ORIGINAL UNTOUCHED CONDITION WITH ORIGINAL PATINA & GRIME. ALL BLADES AND KNICKER BLADES ARE THERE.. NO CRACKS, CHIPS OR BREAKS. STAMPED ON TOE & HEEL WITH OWNERS NAME " GEO O MONROE ". ALL 6 THUMBSCREWS TURN AND WORK BUT A LITTLE TIGHT, JUST NEEDS A LITTLE LUBE JOB. A VERY RARE PLANE THAT DOES NOT SHOW UP TOO OFTEN AND WHEN THEY DO THEY ARE ALWAYS MISSING PARTS & BEAT UP.
