Despite what virtually all claim to the contrary, many (I'm tempted to
say most) orchestras tune higher than A = 440 Hz. (A professional
musician friend of my quips that there's a reason it's called tuning
*up*.) The Boston Symphony is famous for tuning to A = 444 (or is it
445?); the Vienna Philharmonic also tunes well above A = 440. I'm sure
there are plenty of other examples. In addition, pitch drifts over
time, usually higher, but a good professional group will still play in
tune with itself.
So what you say doesn't surprise me, and, frankly, if it were me, I
wouldn't sweat it.

And setting the speed on the Ampex Model 300, which is done by
adjusting the "dig" of the capstan idler into a flywheel, is even
dicier, particularly since most people don't RTFM about how to do it
(hint: it isn't the intuitive way) and if adjusted intuitively they
don't hold speed adjustment particularly well. (The Model 300 does
hold the speed adjustment well if it's done using the procedure in the
manual.) The Ampex Model 300 was used for at least most of the RCA
Living Stereo recordings and I believe absolutely all of the Mercury
Living Presence stereo recordings that were issued and that were not
recorded on magnetic film.
