Be warned that this item on Ebay is almost certainly a scam.
Leica Noctilux M 50mm F 0 95 50 0 95 ASPH 4022243116023 | eBay
The lens shown is the same lens (serial number and pix) that I bought a couple of weeks ago. I haven't received it yet although there's a package that I have a tracking number for in transit. I spoke to Ebay about it today and they said I'm protected if it doesn't show up or if it isn't as advertised. They made a report about this ad but since it hasn't been removed yet, let potential buyers beware.
