Precision wire wound resistors require considerable knowledge and experience to produce high accuracy, high stability and low TCRs and the more exact precision you want, the harder it is to make, there are a great many variables present in manufacturing such resistors and is best left to those who are experienced at it.
Don't know the age of Edwin G. Pettis, but at a certain point it would be great he transfers all his knowledge of making precision wirewound resistors to someone, before he retires or ... . Otherwise we end up with the same situation when Jim Williams or Bob Pease passed away, a loss of knowledge.
I guess I'm not alone with this opinion, that's why most of the guys here on this forum try to find out as much as possible from Edwin on one or the other way.

hello -branadic-,
if you don't mind, let me say that it is the newer generation (that is us) who are mostly at fault. we do not value our elders the way we ought to.
we do not revere them, we do not cherish them, we do not appreciate them, and that is mostly the reason we are creating our own loss,
because, because of our callous attitude towards our elders, they are not sympathetic to us (and rightly so!).
it is we, who have to mend our ways.
really best wishes, i do not intend to malign anybody, and especially not you.
regards.
