Been going through original fasteners and comparing observed finishes with those in the chassis assembly manual and finding some variations. In this case the assembly manual calls for S8 (zinc) finish on the master cylinder mounting bolts. What I'm seeing looks more like dark gray phosphate, maybe even towards an olive tone, but certainly not bright zinc. Car is Jun 64 K code, with the original dated master cylinder.
Is this what we typically see for a car of this period?

Zinc is the most common, even for early cars. What are the markings on your bolts?

I've attached a couple of pictures. Letters look like "NL" to me. Tough to get a clear pic that shows the color, but you can see it best on the tip.
Thanks Charles.

That's the common style bolt, but they are usually zinc.

So you think this has just discolored or is it an olive chromate over zinc? I hit the tip with some steel wool before taking the pic and it still had this color.

Hard to say. It looks like it was possibly removed and cleaned previously.

I was the one who cleaned it. Had lots of crud and brake fluid on it before removal and couldn't see the markings. The tip was just dusty.
