Hello MarkN

It is a worthwhile set of questions you ask.
You have asked for thoughts....

I hope members will take up some or all of the challenge.
I think this will take some time....

The Victa Code system is limited in scope and deceptive in operation.
It summarizes a few components with then current part numbers.

Another significant problem is part number change. For what reason?
Is it a design change; a colour change; a supplier change; a material change;
a packaging change ...? It's all about joining the dots.

It will be interesting what folks may uncover here.
