was wondering if anyone would know what caused these black specks on the leica workmanship?

Ouch. It is corrosion coming up through the plating. That strikes me as a kind of late number for that problem. It is not uncommon with early R4 and M6 bodies. There is no "fix" other than replacement of the affected part$, I mean parts. :(

And it would make me wonder just what kind of environment this camera has been in to cause that kind of corrosion AND what else might be corroded or starting to corrode inside.

Perhaps email a photo to Sherry Krauter or DAG and see if they have any thoughts or ideas?
 
It is one of those Leica things that has been blamed on sweat, salty environments, aliens etc.... but in truth is caused by poor quality control in the flushing and plating process by the manufacturer. I have seen all of the older R4 thru to R6/7 & M6 with this problem even well cared for and quite new ones.
It should never have happened of course, but it certainly should not be taken as a sign of abuse or water damage etc... It's exact cause has been a lively source of debate for many years now the most logical I have heard is that the metal plate was niot flushed correctly or enough before plating thus leaving impurities allowing corrosion to occur. Leica never really fessed up to the problem or it's cause. One day someone in the know might write Leica the real story!
 
Welcome to the wonderful world of zinc. The zinc alloy comes into contact with the moister in the air and begins to deteriorate through the black or silver chrome plating. This problem is predominant mainly in early versions of the M6. Later, Leica perfected the process, but it still can happen with later examples (like this one). Virtually all production M6 cameras have topcovers molded from zinc.
 
No two pieces are the same.

This is a pictures from my 1984 (first 1000) M6.

With corrosion whose patterns are absolutely unique,
no two pieces are the same :)

Come on ... one of my two M6 bodies has some bumps like this, too.
Not on top but on the rear of the top plate.

Thats what I say. These Cameras are 100 % unique.
Some have it on the top plate, some cameras have in totally other places.
This beautiful patterns under a deep black chrome plating are a symbiosis between natural proces and a
handful of artisans in the world who have mastered these techniques for forging patterned metals. :p

I buy this camera from a Professional he used it 18 years almost almost daily.
I love this M6.
