I would not my Model A engine rebuilt from an 80 plus year old WORN OUT tooling. I suggest a modern day shop with CNC and such machines. Makes sense...
Just being 80 years old does not automatically make it worn out. And, wear items can be replaced or adjusted. This old tooling may require more skill and time than the new stuff, but look at all the complaints on here about shoddy workmanship by "modern" shops!
