I'm not sure if this kind of post is even kosher here, but with the recent interest in Cosina 55 f/1.2 lenses here I saw this on ebay and communicated with the seller. He states he has 10 or so available. Three have just closed for $215ish and he has posted 2 more.
Here is a link to his Other Items page if you have an interest.
OBTW, I have no financial interest or motivation to post this.
