=== LOW PITCH & HIGH PITCH ===
Many historic instruments, especially wind instruments sold in the 1910s-1930s came in two separate pitch classes, Low Pitch and High Pitch. \\
Companies that commonly made Low & High pitch instrument include C. G. Conn and Buescher. \\
\\
Low pitch instruments match our current understanding of orchestral pitch and are pitched to A=439 or A=440. \\
According to most academic sources the high pitch standard was set to A = 452.4 ((https://www.google.com/books/edition/A_Dictionary_for_the_Modern_Trumpet_Play/FfzbBgAAQBAJ?hl=en&gbpv=1&dq=standard+%22high+pitch%22&pg=PA82&printsec=frontcover)) \\
Many claim High pitch instruments are pitched from A=456 to A=460, especially on saxophone forums ((https://web.archive.org/web/20190615114129/https://www.saxontheweb.net/Resources/Pitch.html))\\
This would mean high pitched instruments play almost a semitone sharp, but are still significantly flat for that pitch. 





===NOTES===
This is a rather confusing setup and I have yet to find good concise information about what the two tunings were in an exact sense. \\
Expect this to expand to an essay when I know more information
