Hi 26th-Z,
Your post reminds me that I have got FAX message from Mr.Matsuo a few years ago.I would like to share with all of you on this site.
First paper,
#1 You can see the drawings of fog lumps and coat hangers.Mr.Matsuo said in this fax"...I wanted to apply Austin or Lucas type fog lump for Z(S30) like 310 410,but they are big radius and gogeous and heavy,it is tough for Z's thin bumper. So I disregarded the idea..."
"...early chrome round coat hanger is from 410 (pininfarina design) .Same as 410,Z needs cost cut,so the hanger went to plastic.Next I designed a new hanger made of chrome,but it turned plastic when it applyed.I still keep proto type of this..."
Second paper,
#2 In the middle,you can see the audio players.They are all Mr.Matsuo made.They are all proto type.The left one is AM/FM auto tune radio and he put this proto into 240(Mr.Matsuo said 240Z,not Z or S30 anyway) This prototype unit is exist still now,and Mr.Matsuo gave me this.I should keep it.
The center one is a 8 track stereo it has got out put amp.
The right one is a cassete deck for a car which became the first production model for the car.This applyed 610/710 as a option he said.
#3 The bottom,you can see the 240Z ownament.I asked Mr.Matsuo about this proto emblem when I found this in Mr.Matsuo's article.He said,"...this quater ownament was a design study,made of wood,I do not have this anymore"
"...410 SS and SSS was my original concept and I designed emblems and I was deeply involved to produce these car,and this success brought me a promotion to a cheif designer of a sports car studio.That is why (SS and) SSS is very important for me."
If you can read Japanese,you will got more information than my poor english.
Thank you,
kats
