Steve,
Here is the matching plastic case that the 185 came in.

As elnan mentioned, these cases are fragile. The plastic has become brittle (if it wasn't always) and the supports in the base crumble - a workaround is required. More suitable (and practical) is the maroon-and-grasscloth case that came before, that typically housed the 99. In fact, I wouldn't be surprised if, in the transitional period from 99 to 185, some 185s were sold in these cases.
