i think that 010 base was not black in origin. i think that just all painted it black by themselves. 010 i restored (one on the left) was in a good shape before i painted....and it seemed not to be painted at all. maybe only a simil-transparent coat, very light. no sign of black paint. so i tried to make a bronze coluor as u put yellowiish transparent on the nude iron. in other words i tried to do the same effect that i saw when i bought it from "the boss".
i bought the new cap at a bosch warehouse but was the new type more near to sealing wax red than to brown...so i had to paint.
anyway,there is no code for bachelite....it wasn't painted....but moulded in final colour.
every part i paint people ask me code!!!!!!

in except for body vw coulour or wheels.....i simply never look at codes....i use fantasy...but most of all i use my eyes.....i take the original part in my hand and go to paint shop (great one). there are always same colours on their lists.( with example of colour) in that case of cap of 010 there is no right code at all!!!!!!!
simply becuse first of all bachelite colour is not omogeneus but striated....and then because every series of cap had different colours...
so in conclusion cap of same era could be little more darker or lighter.
anyway....the base i used is a chestnut brown (not vw one) with a little black added.
it is not dark as tidi's one (on the right) but it is near to old part i had before. and i like it.
