I acquired a Ball-Record 435C 21J RR PW a couple years ago. It has a 24 hour dial and is cased in a Fortune - Sturdy 10Kt GF case, s/n 6052.
My limited research shows the 435C production starting about 1955, and about 3,400 produced.

The information available at the time was dated, and I wonder if anymore information has come to light to confirm dates of production and numbers produced.

Hi Joe , By chance did you see the info on the Ball Records , there is quite a bit on them if you search Ball Record

Thanks Kevin
I had viewed that and other related online threads and as you say, there is quite a bit of information about them. I just can't find any specific answer as to what date the 435C definitively went into production and ended. The production numbers on the older posts seem to be clear, but I have observed that as time goes on, numbers like these tend to change as more information comes to light. TKS Joe
