In the 1950's and 60's it was not unusual to see aircrew of more advanced years sporting the 'O' brevet. I assumed it was because they were proud of having qualified as an Observer and wanted nothing to do with any new fangled 'N' brevet.
I bet there are are some WSO's who have declined the new badge and continue to wear their 'N' and 'AE' brevets. Same thing, really.
Incidentally, Jeff Jeffords book, mentioned in the initial post reply, is a thoroughly researched and definitive work on the subject. An excellent read.
