Both has the same focal length, aperture number and lens mount.

the mount diameter suggests to me it's for the Argus (C3) not a mount I'm familiar with specific lenses in, so I can't get reliably closer.
I'd guess at 35mm f/3.5 as these are among the more common, and had multiple versions.

Like 1 small

I think I need to give more tips:

a. The lens shown here are the lens head only without the focusing helicoid.
b. They are not wide angle lenses.
c. They are made for 35mm film cameras.

Maybe not enough information. Sorry!

Edit: front element diameter may clue what focal length since we know lens is for 35mm camera.

Not many lens made for 35mm film cameras has a removable lens head.

Last two tips:

a. The lens on the left has 3 elements while the lens on the right has 4 elements.
b. Both of them are first party lens from the same maker.

Do I understand correctly these are interchangeable fronts for a multi-focal length lens body containing focus helical? Or from a camera with focus parts inside?. Smile

3 elements and 4 elements; perhaps the viewing and taking lenses for a 35mm TLR?
