How do one use a Kaiser Focuscope?

Kaiser Focuscope, how to use one? Need a bit of help.

You mean one of these?
I have one and I just place it on the easel, the light shines into the rear facing hole and you look through the forward facing hole. I tend to place it over a part of the photo with a clear line such as hair or the weave of clothing, that seems to work best.

Yes, one of those. Thanks!

Don't forget to put a piece of photographic paper, same as the on that you intent to use, for more accurate focus.
