A while back I purchased an old 8X10 Seneca for spare parts and included with it was a Goerz Celor f5 Series 1b NO 3 8 1/4 inch lens in an Alphax 4 shutter. The glass is in good shape and the shutter performs well and speeds are close. I can find very little information about this lens and wonder if any members can enlighten me. It certainly seems to cover 8X10. Any information about this lens would be very welcome especially coverage, quality and value.
