You know, this is a really good point. When raising money I've always considered selling possessions to be higher on my 'desperation scale' than either earning more or withdrawing savings. I believe, with the construction trend firmly placed in plastic, any metal lens from the era of film photography can only appreciate in value (over some time scale). Plus 'They don't eat any bread and butter' Nona always said.

The Voigtlander in my opinion is too close in focal length to the 35mm. I have the 35mm Summaron so I would keep the Summicron.
I've a preference for the 40mm angle of view.
I like it too but in this case I'd sell the CV. The older Summicrons are plenty sharp and render beautifully. The CV has very little character in comparison.
I would sell the CV and keep the Summicron based on intrinsic market value, but you may find that it won't fetch much anyway so is it worth selling?
On the other hand the 40mm CV has a character, both in physical size and rendering, very similar to the Canadian made 35mm Summilux, soft and glowing wide open, sharpening up and becoming a lot more conventional stopped down. OK it may not have the fine bokeh of the Summilux, but it isn't far off. The other thing about the 40mm focal length is that it fits most of the Leica 35mm framelines more tightly, slightly inside the frame or dead on the frameline instead of slightly outside (at average medium to distant focusing distances). Some people find this easier to visualise and deal with when quickly composing the image than imagining how much lies beyond the frame.
