Good Morning,

They look like bore cleaning devices to me. Maybe for the barrel of a pistol.

They are made from stainless steel , if they were used to clean a gun barrel they would damage the polish in the bore and the rifling.

It looks as if the twists are flexible, and would elongate when inserted into the bore, taking its shape and size. This would exert minimal pressure on the bore and clean any residue. Maybe not for a gun barrel, but some kind of bore for sure.

Are the individual strands sharp? Maybe it is a bore maker or enlarger or smoother?

if fabric were wrapped around the device , they could be used for cleaning different types of hollow bore.

the exterior is smooth.

I was gonna suggest tubing cleaners, especially copper, but looks like that's been pretty much covered. Likely powered with a drill motor.

I think cleaners for automotive valve guides. Was it an auto repair shop?

No

It may have been a general engineer that did everything

I agree. Valve guide cleaner/burnishers. I used them back in 1975 rebuilding cylinder heads.

Just to give an idea of dimensions: that's an Ausy. 50 cent piece which is about 32mm across

the diameters were around 3/8' , 1/2" and 5/8" Gynaecological uses have been ruled out after some consultation with my dear (frightened) lady.

It looks like there might be ball bearings inside the wire portion...? This would allow for some adjustability in diameter....maybe

would guess they are used to lap inside diameters. It looks like if it were rotated clockwise with an electric drill, the diameter would reduce and the opposite would be true if run counterclockwise.
