I was in Singapore in 1969-1970 and early one morning saw a comet just about on the zenith, it was clearly naked eye, I cannot remember whether it was 1969 or 1970
I was not into astronomy in those days but had some interest in the night sky, I know Comet Bennett was around in 1970, was there any other naked eye comets around in 1969-1970?.
I have checked a few sites on the net, but carn't find out if there where any naked eye periodic Comets in that period.
If you have any information? I would be happy to receive it
Cheers astroron
