Help wanted on Rollei camera

[eidos]

Hello Forum members,
last year I have inherited a Rollei camera, which has been successfully used last time a few years ago (*), and I would like to understand a bit more about it.
I know it was purchased in Europe more than 60 years ago, but I would like to understand if this is a model from the 50s or the 60s.

Now. I think this uses 6x6 film, but would like to hear the comment of somebody who knows the model.
I think the shutter should be working, but can you share a link or similar explaining how to check if it actually works?
Finally, the reflective screen shows scratches at the top (see the third picture). Can this screen be repaired at a reasonable cost? And does the camera have any commercial value even if the screen has these scratches?
Thank you.

(*) I also remember hearing about 6-7 years ago that the exposure meter has become unreliable, basically unusable.

Going from just your pics I believe this to be a
Rolleiflex 2.8F (made 1960-81) Approx value: $1000-$2000 (depending on condition)

Yours has the light meter just above top lens. The “scratches” you describe in ground glass are the lines for framing your shot. The camera uses either one of two film sizes- either 120 or 220 roll films. Look in back of camera to see which film type it uses.

ken Riley,
thank you for your comments.
It took me a while to notice your post (it seems I do not get emails when someone posts in this thread).

As info sharing, I also got comments in a separate specialized Forum: this is a Rollei 1958-1961 T model 1 (from the serial number). Tessar lens (Zeiss).
I confirm there are (small) scratches in the top part of the glass screen. This seems to be a common issue, and the screen can be replaced e.g. with present-day parts from BrightScreen.

Thank you for your help.
