Wingnutt, in general MB tools should undergo the same rules that apply to any toolkit.
The tools should retain the finish that they had on delivery, when such a finish is still detectable or anyway known.
They can show a little use, and for motorpool traces of their military life can be tolerated or even welcome according to one's personal taste.
Regarding the Willys tools, the very famous Greg Kareofelas kit ( g503.com/tools ) is undeniably a very good clue for all MBs, but obviously not the perfect evidence for earlier MBs.
I rate it as having a better provenance than the Bizal kit, without for that detracting anything from the Bizal kit.
My opinion, possibly shared by others, and I will not repeat here the old wisecrack about opinions and...
The WOA drawings are an excellent source of information, as long as they are considered for what they are.
I sure wish Willys Motors would have shared more: I still wonder if he might actually
have more, and I hope he actually does.
If so, it is really a pity that someone pissed him off to the extent that he decided to quit.
Joe Friday elsewhere posted this:
There are 4 or 5 different MB tool kits (conjecture) for different contract MB's, and everyone seems to want to bend the facts to line up with the tools they found.
I think this is excellent food for thought, and I hope he will further develop the concept.
Returning back to focus, as per title of this thread, any tool that might have been considered correct for a given tool kit depending on its condition might also be restored, cleaned, slightly beautified, repaired... etc. etc.
How to do that can be learned, shared, suggested, demonstrated, pictured etc..
Whether or not it
should be done is a personal choice that should involve experience, common sense, honesty.
As said elsewhere,
plausible is the key word in my book.
