2 different microphone balances: some sides are very vivid - others are recessed/lacking impact  (4th disc, pt.1):  very quiet passages are hardly suited to shellac - probably due in part to the original processing - as limited the frequency-range to 12kHz - sufficient for piccolo outbursts.

HMV  DB.8633-36  Auto  (DB.3511-14)  Album no.328    1940 pressings/RCA Matrices  (originally: CS 07588/90-1, 07591-3, 07592/4-1, 07595-2)   Recorded: 19 April / 7 November 1937   - Academy of Music (Philadelphia)
Side 1 +2dB, Sides 2,3 +1dB transferred compared to Sides 4-8  (the latter were also somewhat superior recording sessions). 
Surface-noise is mostly quite innocuous thanks to the high-level sound/RCA's HF EQ...plus some decent EMI shellac.
