About the film speed setting, it is a reminder, isn't connected to a meter. The camera is meterless, you'll need to use an external meter or Sunny 11.
Exactly what I was about to do. Butkus' site is great when you have an old camera.
I have a Super 23 with two 6X7 backs and one 6X9 back. Lenses are 50mm, 100mm and 250mm. Then a nice selection of other accessories. I've been using this camera since the late 1970s, and it still works great and I love it. I did have the shutter in the 100mm lens serviced and have put new light seals all around.

It's a big, heavy clunker, but I love it. Put it on my ancient Tilt-All tripod and away I go. Enjoy your 23!
