Best "vintage look" rangefinder lenses of all time

What are the best rangefinder lenses (Leica, Canon,Voigtlander, Nikon, Zeiss etc.) for capturing images with the vintage look? Some are well known classics ;others are great buys you might not have thought of. I welcome your nominations and I'll be happy to share my own. Just ask the professor-

The Meyer-Optik Domipan I used is like new. The classic look it gives is related to the design (Cooke triplet variation). Even though it is a cheap lens, at smaller apertures it does a really decent job. Some people do like the bubbly bokeh it produces wide open, but at intermediate large apertures it is not so great.

To me, the Cosina-Voigtländer Nokton Classic 35mm f1.4 renders some nicely unsharp results. It's a pleasant lens, reminiscent of the early Leica Summilux design. In fact, an employee of Central Camera in Chicago confirmed to me that in his experience, at least in terms of appearance and use, there isn't a significant difference between this Cosina-Voigtländer lens and the 'lux design from the early to late 60s.
