Aperture disks or rings of Voigtlander Orthoskop No.3

[mhayashi]

This is a very specific question so I know I’d get very few answers but let’s try….

I have recently got the Orthoskop No.3 without aperture disks but only with the disk locking cap.




Does anyone happen to have Orthoskop No.3 aperture disks or rings?
Here are the examples in the ebay listing but the seller doesn’t reply my question, although I told him his statement about No.C was incorrect and he changed his description of his sample as No.3.

The original configuration was the 4 aperture disk set as confirmed in the 1858 catalog.

My last resort to this question is measuring the hole diameters from the pictures in the link above then approximate the actual hole sizes.

Thanks in advance for your help.
