Contax II, III, IIa, IIIa Forum?

[aoresteen]

Sorry if this has been answered before but I can't seem to find a forum that covers the Contax I, II, III, IIa, and IIIa rangefinders. Where is the proper place to discuss these cameras?

The Zeiss Ikon forum seems to be only for the new Zeiss Ikon RF not the older ones.

Thanks!
