Shinpachi, thank you for the compliment on my work. Also, thank you for being honest with me. I will work on that. I hope you have the opportunity to see the car one day. It is in Japan (near you, I don't know?) the owner Takehito, attends car shows there on a regular bases. So there is a good chance for you to see it in person, if you go to a car show.
No news about him and his car so far but I may come across any in the future.
Nobuo Harada who is now known as a leading Zero restorer in my country was like him decades ago as a mystery gentleman.
