Sounds like you have a copy lens and that can make a nice low power (maybe 50x at best) scope for fun times.
The best thing with these lenses is to set them up with one EP and enjoy it that way. This means that you don't have to provide a long distance focus system so that all EPs can be used but just have a little bit of focus control with sliding the EP in and out a bit of the holder.
Little scopes like this are always fun to have and make for a neat little scope that you can just leave in the car, making a talking subject for when you take the co-workers to lunch. You won't have so much money in them that you will consider them to be that valuable but they will do a nice job of showing the skies at night.
