markk, got one that seems to roll ok. Well it does to my untrained eyes
The others are well beyond repair though.

The one that looks ok has carbon deposits chipped off the bottom of the stem which suggests it has had contact, but rolling it doesn't show massive movement.

Happy to post to you if you pm me an address, then take it from there. If you like it, you keep it, if you don't - bin it
If you decide to keep it, it will need a clean though as is it covered in deposits.

Up to you
