·I must admit, I had some doubts myself. But I just (feverishly!) checked, the dial feet are intact, AFAIK 50x and 55x dials are not interchangeable without tinkering with them. So I don't see how it could not be a 50s dial; it may be a 60s service dial though, I never saw any. No sign of redialling.
Some examples of 2852s with dome dial / stick indexes:

As I said, I agree that there were also dome dials with stick markers, but they looked different.
Sorry, but no harder evidence from my side. I believe it's a service dial.
I'm sure some experts will chime in.
