and only imo
radium on the second hand has thicker amount applied than the rest. I mean the "height" of radium applied is bigger.
Length of the minut hand would indicate a line of smaller watches than the subs.
Any hand if polished would lose original lume and also original thickness and texture (though there are also re plated hands around of course). These hands have not been polished.
I have seen original silver and gold colored hands from this period, and I'd say these are originally silvered.
Also some 6350 hour hands have sometimes a longer straight section than the set showed above, but these items are still not so clear. As the info you provided along Tommy and Ale Giraldo here
And Philip's most recent post (along his many posts on hands)
There a lot more to find out about this specific but fascinating Rolex aspect.
