NOS dual point distributor. Help with part number plea

The distributor looks NOS, all but the shaft. I guess the shaft could have been replaced along the way, but why? Why would someone rob an NOS shaft and replace with a pitted one? Are those shafts hardened steel? Are they machined? Here is a pic of the topside of the distributor.

That looks NOS , the shaft must have been in a box that got wet and no one ever dealt with it , one could replace the shaft to make it look like new again.

not looking to stir up a hornets nest here - and hope I'm wrong - and have no problem admitting such - but a few years ago someone was reproing distributor tags, and the one on yours is a little different than the originals I've looked at - the "shoulders" that turn up toward the retaining screw look very sharp - I'm pretty sure one should be rounded - on the left side - I looked long and hard to find a correct one for my car - the tag on my dist. has a rounded shoulder on the left side and is original - are you sure it's nos from a dealer - the 3438356 I believe is a dealer replacement # and not a assembly line #, I think the assembly line # dist. is 3438349...maybe some other members will have some info handy

No, I want to know the truth about this thing.... so if you think the tag might be repop I need to know. I have a few dual points from different years and I took some pics just now that I will add. They don't look too different from the 1970 in question. The coating has worn off or is just different throughout the years. Here is a 67 hemi tag.

and a 68 440 dual point.....

and here is a 69 440 dual point.....

the stamping of CHRYSLER looks different in the 440-6 tag as opposed to the others you provided - looks like a block of letters pounded in where the others are nicely spaced out - then again these things were run out ASAP without too much quality control as far as stamping - as evidenced in double taps and missed #'s like other items - do you suspect the tag yourself or the distributor - maybe I AM wrong...

Actually I don't suspect the tag or the distributor. I am hoping someone has seen pitting like this on a shaft and can tell me it is pitting or it is manufacture defect. To get pitting like that you would have to have serious residual rust yes?

The tag should be under the clip.

Now,which one is real ? Not hard to figure out.

And an untouched original.
