No problem posting this on the list. I wish vintage masers would
show up more often. Too bad it's not practical to bring it up
here where I could measure it against mine.

I see it comes with manuals; does it also include the physicist?
(I've heard that, in the early days at least, that each maser
required one full-time physicist to keep it running ;-)

Do you have any comparative NRAO performance data on this
unit? Perhaps not, if it was used stand-alone. But maybe data
was collected against other NRAO masers from time to time over
the years. Any chance you or someone else could get a copy
of those test runs?
