"Regarding the MCO mats...what years were these available for purchase?
Was it sometime in the 1980's, or more recent?"

The page from the MCO catalog that I posted was from their catalog
that I got around 90 or 91, so that's when those correct mats were
available. How many years later were those mats available? I don't know.
Maybe those that bought them can chime in on with that info.
Anyone on this message board who worked for MCO , maybe you can give
more info on the manufacturer of the mats.
