Here is Kodak's DK-15 Tropical Developer from 1941

Water-------------------750 cc
Elon---------------------5.7 g
Sodium Sulfite (anh)-----90 g
Kodalk------------------22.5 g
Potassium Bromide--------1.9 g
Sodium Sulfate----------45.0 g
Water to 1 L

Use up to 90 F but at temperatures up to 75 F the Sodium Sulfate may be omitted for some films.

This formula or derivatives of it were in use through the 50s for tropical processing of films. The USAF manuals for photography are 95- series, and the AFIT (Air Force Institute of Technology) also issues a set of books for the course in photo science. I have copies of both. They are rather hefty 8x10 size books and take up quite a bit of shelf space.
