Studio bottle vase, RJW mark, John R Ward

I've just bought this studio vase. Quite heavy, about 21cm tall, slightly flattened/indented on four sides, two of which are decorated with a probably abstract pattern. There's a clear impressed mark, reading, I think,  RJW, although the "J" may be debatable. At first  I thought this must stand  for Robert Johnson Washington (not that I'm particularly familiar with his work). But this mark isn't given for him in any of the books. So now I'm confused. Any ideas?
