The only piston tools I've ever owned was a cylinder hone. When it came to assembling an engine I always borrowed the tools. I have an engine to assemble here so I looked on CL and found these.
I can't find any name on them anywhere but he said they were at least 30 years old so maybe USA made.
I paid $40 for the bunch and am happy with that.
