Early box cameras that I've seen all seem to have the lens behind the
shutter. The shutters were very simple and the better performance from the
lens was used to advantage. Later box cameras turned the lens around and
put it in front of a more delicate shutter. This provides protection to the
shutter mechanism and allows a more compact camera, but the lens performance
suffers somewhat. For best performance, put the concave side toward the
subject with distant subjects.

The kodak Autographic 3A has a great meniscus that just covers 4x5, I
actually bought one of those cameras with the express purpose of removing
its lens and use it in a 9x12 camera. I don't recall the 3A having the
concave side facing the subject , tho, could someone corroborate that fact,
please?
