[Leica] Anyone have a line on a Kobalux 21mm?

Hi -

I have been on the hunt for a 21mm Kobalux (or Avenon Millenium or MC) lens. 
Color is not important; I am looking for one with 8 aperture blades and the 
0.8mm close focus. If I sold you one back in the day when I was importing 
them, and you're finding it underutilized, I'll make it worth your while to 
sell it back (those would be black body with chrome fronts mostly - but a 
couple of silver ones were in there). I'll look at a bare lens up to a set.

This is more sentimental than anything; I can tell you straight up that the 
Konica 21-35mm and Zeiss 21/4,5 I replaced it with have higher performance 
(as would befit what they cost - which was double or quadruple). And for all 
I know, the Kobalux may have color shift issues on an M typ 240. But 
nostalgia?

So even if you have a lead somewhere, it would be greatly appreciated.

Thanks,
Dante
