What's a cheap, easiest-to-disassemble (and reassemble) lens?

Teaching kids.

It doesn't need to reassemble optically calibrated, but it should work (we use u4/3, since anything adapts).

Wide-ish aperture preferred. A big part of this is understanding what the aperture does, and that's easier if you can have big bokeh balls.

I'm thinking some historical lens from a now-dead MF mount? Or a cheap Chinese CCTV lens of some kind?

I've watched a few videos on disassembly and reassembly of pentax 50mm lenses and they seem quite simple, don't require a ton of special tools or techniques. They also have pretty tough build quality and should hold up well to students using them. And they are cheap. Just my .02
