Excellent condition. Included is a Voigtlander Leica Screw Mount to Leica M bayonet adapter with rear M Lens Cap - TYPE II 28/90.
$475 - price includes PayPal fees and US Priority shipping with insurance. Sorry, U.S. only please.
A few more images here. Please take a look at the last two photos at that link, there is some very minor paint loss in a couple areas, but we're talking millimeters.
This is a tiny lens, more or less half the height of a double-A/AA battery.
This is the 10 aperture blade version. During the time I was searching for the lens, it was the only one I found with 10 blades. Even the information here doesn't mention a 10-blade version, and the ones listed on eBay now are all 6-blade versions.
