I still don't understand why folks are rebuilding their 63-67 alternators for judging and coating the center stator bands caramel color instead of the correct black. All were black as shown below. (Wayne Midkiff photo)

Here's a better picture of a new one. Do judges deduct points for the wrong color coating? We're still seeing a lot of alternators at judging events with the wrong color.

Why would Delco have gone to the trouble to paint just that narrow stripe of black? It would have been simpler to just paint all of the laminations.

At some point in the late 60's, someone at Delco came to the same conclusion and they stopped using the black to cover the stator plates. That's not the point though. For correct restoration, the black would be correct for all 63-67's.

Some bean counter figured the paint savings offset the masking labor. Since the mask was no doubt two clam shells, labor was minimal.
Thats why.

Same reason there are white stripes on rubber vacuum advance hoses

This post wasn't about why Delco did it. It was about showing that Delco did do it. There's way too much proof that all alternators through the 63-67 era had black center stator plates.

I get that. And I'll probably take my Sharpie to the laminations on my '63's alternator to conform.

But I couldn't help wondering why Delco would have gone to the trouble to mask and paint only the exposed part. As cost conscious as auto production is, taking that extra step doesn't make sense.

Now I know why I'm not a purist. This is too much for me.

I agree, some of the details are more than most folks care about but there are many that are trying to learn/document the facts before all of the original cars and members are no longer with us. Once incorrect information is published, it's near impossible to correct it.

And like the white stripe vacuum advance hose that Frankie The Fink posted above, no such hose was ever used on any 63-67 Corvette but if a vendor sells them, people automatically accept it as being correct.

I decided it wasn't masked. look at the over spray.
By using a very narrow gun tip, probably on an automatic machine, they saved paint and disn't need to mask anything, and saved paint.

I was only there for less than an hour in 1966 or so, but that new Delco-Remy alternator plant in Anderson, Indiana was something to see; huge spools of copper wire and raw aluminum ingots came in one end and finished alternators came out the other end at an incredible rate. At the time, it was probably the most-automated major automotive supplier plant in the world.
