Would penicillin have been available for patients in 1930, if Fleming had produced his '29 paper - and then died ?

If only pneumonia had killed Alec, not John....

Imagine - if you will - that you're at a medical meeting - one of hundreds and hundreds that Alexander Fleming routinely attended between the Fall of 1928 and the Fall of 1942 and you happen to overhear Fleming regaling a small audience in the corridor about his 'wonderful' penicillin.
