Camera Adapter Rings And Things ~ Lot of 4.

These are old. My dad was a photographer back when he was young (1940-1960 era).

To be honest I dont know how they are used, but hopefully someone will find them of interest.

Photos 1 and 2, I am not sure what it is. I don't see any markings.

Photos 3, 4, and 5 are of a ERMAC 39.5 MM.

Photos 6, 7, 8, and 9 are of a Mil-O (looks like) 26.4 mm and it has a broken tooth.

Photos 10, 11, and 12 are of a Kodak Series VI Adapter Ring 1- 21/32 42 mm Made In USA.

I tried to show the inside of each.

No guarantee on condition. Sold as is. Thank you for looking. Any questions please ask. 😁
