Can anyone advise what the effect of a 301 Redirect on a NoIndex url would be?

Are you pointing a 301 to the noindex url?
Are you 301 redirecting the noindex url to a new url?

301 redirect is handled in the htaccess file which is processed before a noindex tag that is placed in the page header.

actually there's another case - you could have a 301 status code with the X-Robots-Tag: noindex HTTP Response header.

it would be interesting to (re)test at least two of these cases given this recent change of 301 treatment by google:
Redirected pages in Google index?

if the response is a 301, there is no document served and therefore no meta robots noindex.

Are you asking about a URL that was already noindexed, either via an X-Robots response header or an in-page "robots" meta? Or about a redirect from a formerly indexed URL to a new no-indexed URL? Is there a change in indexing status or only in URL?

Search engines crawl everything. A page with a long-standing noindex label won't be crawled as often. But it will be crawled eventually, and then they'll see either the noindex label or the absence thereof.
