Old film in Zeiss Netar

Yesterday evening i bought a Netar with a 6.3 75mm lens from a lady who said itwas her fathers. 5 or 6 images had been taken and she guess it was black and white film.

This mirning i took a walk to finish off the roll and test the camera and to also test a Brownie Hawkeye we bought last month at Value Village.

Turns out the film in the Netar was Panchromatic Made in England. Other than the numbers and the fold over on the tab there are no markings. The backing paper is a dull yellow.

Other than suggestions on how to develop what is probably Ilford film ( i have both HC110 and Rodinal) and suggestions about the Netar? The only other folders i have used are a Kodak Tourist and a Vest Autographic 127.

As there is no apparent way to know what the film was directly from the backing paper it might help if you have any idea of when her father might have been using the film. For instance can she remember how long it was before he died for instance. I ask this as it might help Ilford, should it actually be an Ilford film to establish which one it was from a description or better still a picture of the backing paper. All fairly long shot stuff, I know

However the simplest method might be a Rodinal stand or semi stand development at 1 +100 for an hour to see what turns out

I've read that some folks are going cold stand, Rodinal 1:100 but leave in refrigerator for 24 hours. Or assume it was a mid-speed film, HC 110 B, 10 minutes at 68F/20C.

If it was me, I'd try to cut off a few frames of what you just shot and develop one way or another. If it works well, stick with that to recover the old exposures.

You can do stand development with HC-110 as well as Rodinal. Use one of the higher dilutions -- F, G, or (unofficial) H. Don't do this cold; the hydroquinone in HC-110 becomes inactive below about 60F and you'll lose the superadditivity (and get blank film or extremely thin images).

Rodinal 1:100, one hour, semi-stand (a couple of inversions). You can't go wrong.

An uphdate, I developed the rill of film that was in the camera last night in stand development. There was a small amout of base fogging andvthe first image was heavily fogged. The film had no company name or even frame numbers hence still no wiser on what it is.

The good news about the camera are no leaks in the bellows, the faster shutter speed is accurate enough, especially as I was not using a light meter and it had good spacing between frames. In other words I bought a functioning foldine camera.

I plan on scanning the old imaged and contacting the seller to see if she would like them. Looks like family pictures.
