Thanks for your insight. My uncle thought that might be the case as well and suggested trying a magnet to see if it stuck. It did not but I later read that cuni doesn't always react to magnets so I'm not sure whether the lines are cuni or copper. I've come too far (lol) with the new lines and brake MC so I'm going to try and use the parts that I've picked up over the past few weeks.If those are Cupronickel (and by the gold-ish colour in the photo, I believe they are), the Burst-pressure is higher than steel, and far more corrosion-resistant to boot.
I used to use steel exclusively, until I actually bent-up and flared a set of CuNi lines, about 3 years ago.....
