Got a set of Bertram camera with 3 lenses, similar to this link:
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.
