Yeah, I remember from the "good old days", we individually calibrated taut-band meter movements with a HP designed servo-meter calibrator. At least that's the way we did it for some models. I don't guarantee we did it that way for all models, though.
The way I remember it, this process (regardless of which division's instrument was involved) was performed at HP Loveland. Disclaimer: My memory might be slightly skewed after all these decades. For description of the taut-band meter movement calibration, see the HP Journal article at: http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1966-01.pdf I do agree with the other post, though, that *any* saved/scanned scale is way better than no (or a damaged) scale. In many cases probably a randomly scanned scale would match a given meter movement good enough for most our purposes.

HP was quite proud that scales for their precision meters were individually produced for each movement on a custom made servo controlled photographic calibrator. An archive might be nice but won't provide the meter accuracy of the originals produced for each unit.
