Sight

[yamoon]

This modern reproduction tang sight came on my System Marrkolbe. The insert in the large disk is threaded and can be removed with a screw driver. I would like to order different apertures if the maker is still in business. Any information would be helpful,
Thanks Mike

Mike,
I doubt if I could help anyway, but it would be helpful if you measured the thread diameter and pitch, in case someone has what you need.

Thanks Mike, I have 2 adjustable aperture disks, if the thread matches I’ll probably use one of them.
