Unsure of make and age but I have some rolls of matting, similar to Dandy Dura. Unsure of complete condition as its been a few years since they were used. I would expect a couple of holes and fraying here and there.
Un rolled one [pictured the other day]
14 rolls in total I think with I expect most to be 9m or longer. I have found 2 colours.... 4 of the 'redder' fleck and the rest are the colour pictured as rolled out.
