Hi Robin
I have one I would be willing to sell, complete with twiddly thing! I have no idea of the value. I can photograph and send if you are still interested in getting one.
All the best

I have a used Mec Centra Sling Connect Jacket Attachment for sale. This came with a used Kurt Thune jacket I bought a while ago and is something I will never use.
It shows very slight signs of use and is in good condition. I am asking £25 posted.
