My baker and my brothers both came with a safety harness. Two really crude 2 inch wide braided nylon strap you fed thru a release type buckle. One for around the tree and one around the waist there was a D type ring that connected the two belts. Yup crude compared to todays harnesses but could have saved a bad injury, Hope if you used it and fell some one would come get you down before the belt cut you in half.
I got good at doing chin ups going up and down the trees with that baker. I was in my 20's then.
