My Compaq clone is gray and makes no efforts to try to use an Elna name. No way to confuse it. My Elna SU came with a case that is slightly different from the Supermatic None of my cases have the smooth inserts that some ( all?) that the grasshoppers do.
My SU below has a blue case, TSP didn't come with one.
