Tom,
Welcome to the CB Forum!
It's a lot more quiet around here since the passing of CB guru Bill Moore, but things do stir from time to time. You are not normally going to find many listings for CBs, but they are around and come up from time to time. Are you looking for a total restoration project or are you looking for a more finished vehicle?
Keep plugging away. Going to meets and talking with other VW enthusiats may scare something up. Keep an eye on eBay and Gumtree because they do appear those places intermittently. Watch Buying, Selling & Swapping Cars Forum here at the AVD site. You may want to post a WTB thread there to attempt to flush something out of the bush.
There's one listed For Sale there now, but have seen much thread activity lately about it:

Since they are were so rare to begin with, there just aren't many floating around. Many fell into disuse due to maintainence/repair issues and got parked in sheds, or even out in the open, and were largely forgotten. But as all of us know here at the Forum, there are still some out there and they come out of the woodwork from time to time.
Hang in there!
Good luck!!!
Regards,
Steve
