Super Angulon 90mm f8 lens cells. Will screw right into your Copal No. 0 shutter and includes correct f-stop scale (the one that goes on the bottom). Cells were probably on a No. 0 Compur shutter originally.
Glass surfaces are all in good condition, with no marks that I can see. The rear cell has some black specks in it. Front and rear caps included.
$59 plus postage. Paypal accepted.
