How to use Bertram Camera?

[ericzhu]

Got a set of Bertram camera with 3 lenses, similar to this link:
http://medfmt.8k.com/mf/bertram.html

Unfortunatlely, I don't know how to use this camera. Appreciate instructions of:
1. How to unfold the camera;
2. Which button to tension and release the shutter;
3. How to change the lens;
4. How to dismantle the glass focus back and change it to roll film back.

I tried searching the manual of this camera on net, but failed. If anyone has the copy of manual, pls contact me by PM.

Thanks a lot.

From my memories of the ones I ran across in shops or camera fairs, the handling is not that odd if you are familiar with the Plaubel Makina or preceding strut folders.

I haven't used Plaubel Makina before. Really don't know the function of all the buttons on the camera.
