Super Ikonta film path scratchy???

[Agulliver]

I've just taken delivery of a pre-war Super Ikonta which is in decent condition though certainly not "mint". A quick test without film suggests everything works, including the shutter being surprisingly accurate at all speeds. Rangefinder seems fine etc,

What I am concerned about is that the pieces of metal next to the rollers feel very abrasive as if some sort of coating or paint has deteriorated over the years. I've attached a photo which hopefully illustrates what I mean.

Do the good citizens of Photrio agree this is likely to scratch film? And what might the best/simplest remedy be?

That looks exactly like what has happened.
I would indeed expect this to be a potential problem w.r.t. scratching, although some films will be more prone to it than others.
Personally I'd start by giving it a try as it is now, e.g. using Fomapan film (fairly soft supercoat) and if that gives any problems, remove remnants of this paint/coating and polish and/or re-paint.

The only surfaces you need to be concerned about are the narrow surfaces top and bottom. The film doesn't touch the wide flat surfaces you mentioned because the rollers hold the film clear of those surfaces. For appearance sake you could clean them, paint them, allowing the paint to dry thoroughly before exposing a film.

The rollers themselves don't look completely smooth anymore, and anything that chips off the rest of the surfaces can get stuck between rollers and film and scratch. They can also get sucked into the bellows and onto the film surface by vacuum when the camera is opened, causing black spots on the picture. I wouldn't be surprised if the bellows already contains more particles than the rest of the camera, they usually do. A thorough clean and blow out at minimum is a good idea with any old folder.

I like Rustoleum black oil-based metal paint for those types of things, takes a while to dry but makes a hard surface. You may have its equivalent in the UK. You'd want very thin coats of paint no matter what you use.
