Are the hands and dial correct for this 1940's 30T2

Hi Everyone, I don't have a lot of experience with vintage Omega watches and was wondering if the watch at the URL below has the correct hands and dial for a 1940's vintage. Also, the seller indicates it was serviced but the photos show a missing screw that holds the movement to the case. Is this common with old watches? The screw should be easy to replace unless the threads are stripped in the hole.

Any advice would be much appreciated. Alan

Does this help with the hands question? http://naligazone.com/index.php/data-watch/omega/13-watch/omega/210

The hands seem to be correct (I have checked on Google with the ref and on Naligazone).

But it is actually strange that the missing screw has not been changed during the service. It is not a big deal but could suggest the service was not complete or perfect.

Thank you very much for your responses and letting me know about naligazone. This is a great website with lots of information.
