Dear Friends: A friend of mine asked me to post these photos of this circa 1930 Auburn axle,which is under a vintage 1930s sprint or midget car trailer. He'd like to know the models and years this axle was used. I believe the race car trailer this axle is under is still for sale. Contact Dan at Daniel Phenicie <dephenicie@gmail.com> Thanks!
