MORE RED STUFF EVERYWHERE
The red coloration as seen inside the bell above is typical on older relacquered horns and is not a red rouge buffing residue as the color suggests.
This reddish color or a similar shade will appear somewhere if not everywhere on most of the older relacquered horns. The stripping, cleaning and rinsing solutions used in the relacquering process along with their strengths and the length of time applied, all lend a hand in determining the final coloration. The quality and type of lacquer used have bearing as well.
COLORATION WILL VARY
The Conn alto sax above is another example of how coloration can vary from horn to horn. The coloration of every relacquered sax will vary depending on its molecular makeup and where it has been residing. Colorations commonly seen range from bright orange to dark red and everything in between. A green corrosion is more likely to occur on relac's where the lacquer is gone and the moisture collects.  PIC  The discoloration factor can be a great indication of a relac when put together with all the other clues.
