I contacted the case company today. Turns out Frank the owner, at my suggestion and using my specs put things in motion right after we talked Friday to make the Tyros 4 and 3 cases available as a regular production case to fill a need for some cases that we keyboard players would want in a quality case. I stressed the issues of weight, dimensions and of course a good price.
The parent company is apparently Hybrid Case Co. They have a number of divisions on ebay: islandcases, nycase, pockettrunks, casekits, etc.
They also have a division called Road Cases USA. I don't completely understand this marketing strategy, but I guess it works.
Here's another ad for these cases on Road Cases USA:
