the International Rollei Club

Hello!
I am a new user from Italy.
I found in my dad's drawer his Rolleiflex. He was very proud of it, and, as you can see, it is in mint conditions.
My sister wants to sell it, while I would keep it for me, as a part of him.
He bought it more than 30 years ago, maybe even 40.
But sincerely I do not know either what model is it, either the estimate value.
Can you help me or give some hints? I attach some pics.
Thank you in advance.
Best regards,
Claudio

It is a 2.8F. One of the earlier ones. In near mint condition with the case and filter and lens shade you should be able to get a couple thousand USD for it on ebay, especially if you are willing to ship it to China.
