I bought a Swift stereo ninety No.651587 for $10 at a school salvage. It is missing some parts such as eye pieces, the stage plate and probably more. I need a picture or diagram to see what's missing and to decide whether or not to try to fix it for my grandkids. Can you help me with a picture and parts?

SOURCE: Are spare objectives & eye

most objectives and eyepieces are interchangeable between models of microscropes. There are however a few things that you need to be aware of. On the out side of the objective there are number written on them that look similiar to this:

100x/1.25
160/0.17

There maybe more writing then that, but usually at the very least you get this. The first part (100x) is the objective magnification, the 1.25 is the Numerical aperture, the 160 is the tube length (in mm), and the .17 is the cover-slip correctness. What you are most concerned with is the mechanical tube length. There are 3 common ones, 160, 210, and infinity. It is very important that you get an objective with the right tube mechanical tube length, or there is a very good chance it won't work. If you are working with slides, then it is a good idea to get one that is cover slip corrected, otherwise most of the other information is only real important to very specific applications.The other key variable is the threading. Most microscopes use what is call a standard RMS threading, however many educational or high end objectives will not have this.

The eyepieces are pretty straight forward. You just need to find one that that has an outside diameter of the sleeve that will fit the inside diameter of the tube it is going into. Beyond that, most eyepieces are pretty interchangeable amongst brands.

One other thing to watch out for when buying eyepieces, is that they come in 2 sizes. The most common size for amature telescopes is 1.25", but many low cost Asian made telescopes use .995". Measure your eyepiece holder first before ordering new ones.

ebay is a great resource for eyepieces, i would suggest a 26mm ma.
the eyepiece should drop in. if not you might be missing the image erecting diagonal. when the eyepiece is installed you should be looking perpendicular at the tube.
