According to my former boss Wilfried Koetz from W&W the CW as standalone product was offered, but never officially sold, since all customers chose the CY.
There were customers who had their HP-41 upgraded with an internal 32K RAM box at W&W. However these calcs were not officially called CW.

The only "real" CW unit I had here for repair was one which looked like a CY, with turbo switch and CY logo, but only 32K RAM installed. The back side of the pcb was empty. That unit belongs to one of the CCD module programmers.

So it's very likely that the HP-41 unit on the pic is either an upgraded CV/CX , or maybe a CY without the proper W&W OS.
