Featured in this lot is this pair of vintage Diamond Calk Horseshoe Company spurs. This pair of spurs have been made from vintage Diamond Calk Horseshoe Co. horseshoes from the early 1900s. Diamond was the brainchild of Swedish blacksmith Otto Swanstrom who arrived in the United States when he was 15 years old and began making horseshoes and horse harness in northern Minnesota. Swanstrom formed his company around 1908 to make drive-in calks. These spurs feature prominent goose-neck shanks with a 5 point star shaped rowel. The spurs also feature leather straps for securing to the boot. The spurs read on the inside, "Diamond Hot Forged" showing that the horseshoes came from Diamond Calk Horseshoe Company. Overall the spurs show good condition for their vintage age with no signs of damage. The spurs measure 6 3/4" L x 3 1/2" W x 3 3/4" H.
