Welcome to the forum and I think you should take a look at some search results here on TRF for both Young and Rolliworks.
The difficulty in predicting outcomes depends on the condition of the bracelet. A 50 year old one may need a new clasp. The Jubilee links don't always come loose in a condition to be reused. YMMV.
Google can help you crawl through the dozens of threads to do your TRF research. Type this into Google to see them:

From personal experience with bracelets - especially 50 year old ones - a proper new one may be better than refurbishment hassles. RSC would be correct source or an AD. It won't be the original but would be what your Dad might have done...
I do understand the heritage value of an original one - but my Dad had changed out an original bracelet for a Twist-o-Flex once in the '80's. He just liked the ease of use.
