Cannonball key heights

Hi, thanks for looking and thanks for any clue on this in advance:

Just purchased a used Cannonball Big Bell 107000 Tenor.
Wonderful instrument, only suffers from bad intonation caused by bad adjustment of key heights.
Particularily the left hand korks for key heights are almost gone.
G to middle-oktave key connection kork almost gone.
Right hand k.h. korks have been partly filed so that right hand is too open.
So here´s my question:
Is there a "general" kork thickness for the left and/or right hand openings, that anyone knows of ?
Or does anyone have an original instrument in good condition where he might be able to measure the original key hights ?
Any help on this is highly appreciated !
