I have now received the basic repair kits for the slaves (the bore was fine) and got all other parts from zinc finishing (unfortunately not the same yellow tint as the original one). The last thing to do before I assemble all is to blast and paint the slaves. It seems like they are dark green, but I'm not sure if that is the original or if someone have painted them before. So, can anyone tell me what the original color is for the brake servo slave cylinders (2200 TC with twin servos, Sweden)? Black, green or silver?
