Other than the handle it doesn't look that different from a "Regular" 200 on Badger's web site, and I have a "Regular" 200. I've never used that particular airbrush, so correct me if I'm wrong.
To disassemble, unscrew the needle and pull it out from the rear. The valve button will fall out when the needle is removed. Unscrew the crown from the tip and remove it. Unscrew the tip and remove it. DON'T LOSE THE GASKET BETWEEN THE TIP AND BODY! That's really about all there is to it. You can take the air valve out and disassemble it, but I've never had a need to. The 200's are quite a bit easier to clean than my Omni.
I normally use acrylic paint so cleaning is easy. I soak the parts in cleaner (Windex, Simple Green, and distilled water) while I'm cleaning the body and needle. I use a Q-tip to wipe out the fitting where the bottle goes in (there is always paint in there), a pipe cleaner in the front, then rinse it in water and dry with my compressor. Tip and crown get cleaned with a pipe cleaner after they have soaked a few minutes, then rinsed with water.
One thing to note, and it isn't emphasized on the instruction sheet, at least it wasn't years ago when I got mine. If you aren't going to use it for a several days, unscrew the tip about 1/4 turn. There is a white Teflon gasket between the tip and the body. If it is left compressed for a long period of time it won't seal properly. I've just gotten into the habit of unscrewing mine before I store it.
