I found a camera nearly identical to the Felica at a flea market in Hannover, Germany recently. It's called the Necka-Junior and appears to differ from the Felica in name and color, and in that it doesn't have a handle like the Felica. Otherwise it's identical in shape, size and features, right down to the built-in yellow cloud filter.

Hi, I just bought this camera from a German friend. I have a question, should I cover the back little window? I saw some posts saying should be covered to avoid leaking light into the film.
