That bottom bracket for the lift rod for a frt snow blade or snow thrower is definetly home-made, but the top looks factory, and around the vintage of an Original or 70/100 or 71,102,122,123, probably has two small cross holes for the wire bail to hold the lever in the float position. Newer tractors had the little pressed in latch pin on the front side.
It would look "more factory" if it was properly painted yellow.
Sounds good if I were into that sort of thing! I almost didn't go get that tractor but as a favor I did. The last year redoing and putting it back together taught me measures!!! I now have a hobby I love and my biggest take away is how America really use to like putting out quality...doesn't matter what it looks like,just how it was built
