Vintage Zeiss Ikon Contax 35mm Camera W/ Sonnar 1.5 5cm T Lens Untested For Sale

Ok, I am NOT knowledgeable about cameras, so, please feel free to contact me with any questions. Please ask before offerding, as I have no clue how to check these old cameras, nor do I have the exacting knowledge in what to look for. I will say that it does wind, click and shoot. Other than that, I have no clue. This is a Zeiss Ikon Contax 35mm camera, with a Sonnar 1.5 5cm \"T\" Carl Zeiss lens. Missing the logo on the front of the camera case. Assume the worst, but, hope for the best, as this is being sold as shown.
