Adding one more to this list
Serial 4664, Petzval, no WHS, still has lens cap but no flange. Two out of three elements marked with this serial number. Lens diameter ~60mm, didn't pull them out of the cells.
Serial 6821, Petzval, no WHS, no flange, no hood. Two out of three elements marked with the serial number. Lens diameter ~47mm, didn't pull them out of the cells. This lens is already on the list I believe.
Cheers,
Rudi
