What a pleasant surprise ! I haven't been on this website for over two years until today and there is my father pictured on the home page .
So a good time now to ask again if anyone knows what the colors of his bike would've been, particularly the petrol tank ?
The photo was taken at Chofu , Japan , Feb 1947 . ( J force )
So the timing was pretty accurate, I have put it on the website yesterday. I wasn't sure any more where I got it from, probably from you? I didn't had any other information then "Anthony's dad", nice to have some more info now.
