After using my Weston III for about 25 or more years asa just a reflected light meter I finally found one. It was in the bottom of a Graflex camera case I bought on ebay... and the Invercone was complete with its case. It really is a nice accessory to use. Only complaint (but I'd rather not use that term) is that the Weston III doesn't lock the needle after reading. But, hey... it doesn't do that for reflected reading either so what's my complaint.
