I found a Graphex Lens by Wollensak 4.7 with Full synchromatic. The shutter is in great shape, but I need a front element. Where can I find one. I think the lens is probably 127 mm.

Buy another one. I'm not kidding, loose cells are much less common than complete lenses.

Graphex is Graflex Inc.'s trade name for a shutter, not for a lens. The lens could be an Optar or Raptar (both made by Wollensak) or a Kodak Ektar.

If you go shopping, consider whether you want another example of the same lens or one with more coverage. If you like the 127 mm focal length, look for a 125/5.6 Fujinon W. These were made in three versions, all or good. Or look for a 135 mm or 150 mm lens from, in alphabetical order, Fuji, Nikon, Rodenstock or Schneider.

Thanks. I will take your advice
