Thanks everyone. I only need 2" for composition analysis; about 5" for tensile strength testing and composition analysis.
Again, it will be critical to know the maker and some estimate of DOM.
This is my last invoice from METL for the whole show, for one sample, so it needs to be worth the expense, which IMHO, knowing the composition and tensile strength of Whitworth would be.
Before someone points out the obvious, I get it is for one sample, from one maker, at one point in time.
