hello Possum. greetings from across the ditch. gee that sounds like a opening line from Dame Edna.
mate, I got a 70 F/Back. been through this a while ago. lots of debate over grenadier or signal red. I dont think grenadier is correct. from my research signal red seems the correct red. I have compared signal red with some old sales catalogs and it seems to be the one. grenadier seems abit darker red while signal red has just a tinge of orange .
I have traced the signal red to the following code:: Signal Red british standard 381C paint code 537. some paint suppliers cant get the data, but I used Dulux paint. the local supplier had the british standard.
As for the oil tank, I got a color from Auto Pro auto shop.the paint code is an auto pro one. the color is T-UP 350 G platinum silver metallic. PK9010, 9 300749 390105. very nice color with very small metal particles. did not put clear over to get shine. just used a cutting compound and polish. came up very nice indeed.
if your bike is not concourse this is a very close match to the original silver that was on the later fork yokes. this is what i used as a reference starting point.
I cant post photos here, but if you PM me an email address I can send you some photos of my finished results. also the old sales catalogs .
hope this helps
error corrections welcomed
