Reed 5 in OBP also doubled flute and alto sax. They were restored in the critical edition and the orchestral score is available for purchase from Alfred. (The critical edition’s orchestration listed on the Concord website is incorrect.)
This means Concord’s “Original 1948” version must have been misnamed. I suspect it’s just the old licensed version from Tams, which does omit the flute and alto sax in Reed 5. That version also has a clarinet solo in “Too Darn Hot” instead of the sax soli heard on OBCR (at 2:05) and restored in the critical edition.
