Customer Letter from 1967
Dear Ray,
I thought you may want to know that Mayon Tubing was used in this epoch-making operation, which has had so much publicity. I do not know if you ever met Chris Barnard who spent several years with Lillehei (The Cover Story – Time Magazine).
Kindest regards – in haste,
Yours sincerely,
H.J. Kretschmer
