I found a cool IDEAL 246 camera (4x5) the other day, and plan to attempt to take a few shots with it. I'm trying to find out any information on it that I can... I did find a very similar camera, the ICA Favorit (like the Zeiss Tropica), bu t am wondering if I can do anything to update the camera, and want to know if us ing it is a good idea to try using it. The body is metal, the lens looks great, but isn't a well known brand. It's of german make, Dollep-Anastigmat Helke 13,5 cm, and the camera was manufactured in Dresden.
