Opening and cleaning a model D viewmaster viewer - part 1

If you would like to clean the lenses of your model D viewmaster viewer, see here how to take the lenses out.
If you are not up to this; visit www.3dworldshop.com and buy a model D viewer with already cleaned lenses and a superbright LED-bulb.

The model D is the best common viewer that you are going to find.

The best hope (I know of) for preserving the lenses is removing with a fingernail or nylon "bone tool".
I've seen pieces already flaked off before ever removing from the mounts though. They're ridiculously fragile.
