I3-30, if correct, would be a payload serial number.
Rocket n°M1-6 made two launch attempts, and both were aborted after ignition.First attempt : 11th June 1957Second attempt : 12th March 1958
There were three attempts on June 10-11, 1958.
And again the rocket has been returned to factory and converted to training rocket.
It would explain the strange numbering of И1-7А...
…frist attempt to launch Luna-2, on 9th September 1958.
И1-7А, И1-7Б, Л1-9А, Л1-13А, Л1-7Б... Too many strange numbers, are not they?

Королев по непонятной причине вдруг закричал на Пилюгина: "Ты разберись, что твои схемщики натворили!"Воскресенский сразу нашел причину: "Это виновата машина номер шесть. Она в старом варианте уже снималась со старта. Ее не следовало допускать снова". Все так устали, что никто даже не улыбнулся.
Andrey, in Poroshkov's book (page 113), he writes that launch of 10th september 1958 was the third attempt of "rocket n°6". Since you speak Russian better than me, do you think that it could mean : M1-6 = Б1-4?

I bow to the experts' ruling that the vehicle was not designated 8K78Muntil the 1966 upgrade. But it does seem likely that the 8K78 (1964)vehicle has different engines in lower and final stages and so is sufficiently different from the 8K78 (1960) that it's useful to track itas a separate variant.
while the 8K78M first flew in February '64
8K78M first flew on 04.10.1965 (Luna-7).
