This may save some US buyers a few bucks rather than having to get them overseas. B&H photo in NYC carries these and usually has them in stock. The Squeegee is a light grey color (rather than the the off-white/tan-old-computer color) and doesnt have the printed "Paterson" logo on the face. But they do say paterson cast into the edge of them. Same item, just a newer production piece. Same with the stirrer. Color is light grey, but the same piece as the vintage ones.
You can order them direct from B&H here:
