Need some info on atom drum brakes

Hello, I just picked up a 1980 schwinn cruiser 5 speed. I'm looking at restoring it with my son and was working on the getting the rear drum brake to work. At some point in it's life a rear rim brake was added and the drum brake was disconnected. I was looking for close up pictures of the brackets and levers on the drum if possible. Also, is there a source for parts for these? I know that last part may be impossible, I'm used to classic car restorations so am confident I can make the brackets/levers if I have to and have a good reference.
Thank you

I have an Atom drum brake on my Gitane tandem. They're not complicated, but I doubt replacement brake shoes are readily available. Sheldon Brown has a good article (actually, John Allen on Brown's web site):

And Google images brings up some pictures:

with respect to the Original Poster (OP) in the vintage Porsche world there are shops that can replace brake linings on drum brake shows so as to "preserve originality". Such a shop might be able to restore the Atom brake shoes as shown.

Look in Pano or post a request on Pelican Parts.
