question about copper tubes & hair color variation on Vintage no. 1 Barbies

The question concerns a # 1 ponytail that I recently purchased. She is very nice, but I noticed that the copper tubes in her feet are either missing or pushed in so far that they aren't visible. I was wondering whether anybody out there knows how great a reduction in value the "missing" tubes might cause. Also, her hair, while very nice, is a different shade of blond that most no. 1 Barbies that I have seen (including anther no. 1 that I own) as well as all of my no. 3s (don't know if 3s had different shades than 1s). So I am wondering whether blond vintage no.1 Barbies came in different shades of hair color. This one is slightly more "ashy", definitely not honey or gold colored like I am used to seeing.

Thanks in advance for any information!
