Metal alloy plating seems common in fixed head disks also, at least in the ones from DEC I

Once I can make sense of the timing tracks, I
think I'll proceed with

Just seems wrong : ) -C
If enough working heads can be found, the drum probably can be
remanufactured, as according to this:

the drum was nickel-chromium plated, not ferric oxide. This is what I
would have suspected, as coating equipment and binders would probably be
a far cry from modern technology back then, where precision plating was
already an established art.
