Yes, I used to sell these but I ran out a while ago.  I acquired
them when I purchased this business from Nigel Perry who presumably
acquired them from the original owner of the business, Steve Cox
(who passed away some years ago).  Steve must have produced a mould
for these, but it seems to have disappeared into the mists of time!

If anyone can come up with a mould, I am sure it would not be too
difficult to find someone who could produce the rubber mats.
