Regent or Solaris Grape Scion (Totton and Eling SO40)

Appreciate now is not the right season, but I am looking to graft Regent and Solaris varieties of grape to a 20 year old root stock. If anyone has these varieties when they prune in March and have 2cm or bigger canes from last year could they contact me please. I can collect any day of the week. Or if anyone is removing these varieties from their garden / allotment please let me know. Thank you.
