I have one in my sights. It's the Canadian version with the aperature ring near the front. The glass is pristine, a very slight amount of oil on the blades. the body has seen some use for sure. So what do you think it's worth?? BTW it's black not that should matter. I have already done a search of completed listings on eBay but that didn't give me much usable data.
Let me know who's selling it I could use it as a paper weight
Depends on how much you want it. I've always bought Leica stuff from authorised Leitz dealers which surprisingly hasn't meant more expensive.
Dan's probably right you can get a good user, optical fine but looks worn for £300 or the Can $ equivalent (welcome to APUG BTW Dan). That's the low end of UK prices.
