Thank you very much guys, I am really happy to know that some peoples like the bike.
After that, I have met previous owner (2nd owner, he is also friend of mine) of the bike last week.
He told me that this Courier was originally bought by its first owner at the Muddy Fox shop.
I assume that was the one in London, around Oxford Circus.
Thereafter it was given to this second owner and then handed over to my friend as third owner.
My friend, current owner, seems to be very delighted as well as scared because he doesn't want to scratch it - it is sitting in his bed room
Good news is that the second owner was so delighted to see his old bike fully restored, he asked me if I want to have his Fisher CR-7 to sort it out, which hasn't been ridden for long time.
