1937 Blood Joints, Minneapolis Moline Universal Z & Oliver-Hart Parr 70KD Test Report

This original magazine page from 1937 measures 8.5 x 11" and showcases vintage tractors and equipment front and back.  On the front is a Blood Brothers Machine Company ad for their Universal joints as standard Equipment on the 1937 Minneapolis Moline Universal Z tractor.  The Blood Brothers were based in Allegan, Michigan.  On the reverse side, is a University of Nebraska Test Report for the performance of an Oliver Hart-Parr Standard 70 KD tractor, very unique piece of literature for your collectible tractor to say the least.
