Doubt you'll get a match and will have to make up the profile either plastic strip or hardwood.
B&Q or Wickes sell strip plastic, alluminium and steel.
plus look in the beading box shelving in timber sections. Or even search net for plastics supplier/retailer local to you.
If you can't get any out in reasonable form take digital close up of the strip and take the camera with you when searching.
