Which adapter is that?

[varjag]

Any Miranda SLR owners here? I bid on this one (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=010&item=200004915377&rd=1&sspagename=STRK%3AMEWA%3AIT&rd=1) being sure that it's for Nikon/Contax RF mount as advertised, however I've found it elsewhere described as M42 to Miranda body adapter.

The seller did not respond to my question yet. Could anyone here tell me if my bidder remorse is justified?
