On an Argus C-3, the proper lens mounting technique needs to be followed, or the lens will be slightly out of sync with the rangefinder.

Set the Rangefinder dial to 3 feet.

Mount the lens, making sure it threads all the way on.

Align the focusing ring on the lens to closest focus so that when you place the transfer gear back on the camera, it slips into the last tooth possible on the focusing ring.

Hopefully, this will clear up some of the softness you are experiencing in your photos. And check that the lens is clean. A slight haze may have formed over the years that is not noticeable to the eye, but may show up with a bright light shown at an angle through the lens. As long as it was in storage, this could be the most likely reason for the softness.

If you need to clean the lens, make sure you get the center element back into it's proper orientation, or all your photos will be sharp in the center, with increasing OOF towards the edges. But then some folks like that.
