Hi, Welcome to posting!
Pictures will help us guess at the color. Even if you had an unused spool of the original thread, the wraps wouldn't match. The color you see doesn't look the same as the day it was wrapped. Your rod has aged for 50 years since.
My best advice is pick a thread that looks best to you and rewrap the ferrule stations. Don't worry about the color mismatch. Maybe use a contrasting color and worry even less.
Next best option; if you really want everything to match, then rewrap the ferrules and guides. If the guides are worn, this is a good time to replace them. I don't mess with the signature wraps unless I'm going to work on the rod grip too.
