He (my friend) has one of those (Speed Graphic). It has the original flash attachment with it. It is from 1932. There are a few older cameras, too.I've used Speed/Crown Graphics and their ilk. In my collection are Busch Pressman D and Pressman C models. The latter belonged to my SO's father and I used to shoot Ilford 2 1/4x3 1/4 sheet film with it; the former was a regular staple (as opposed to a fancy staple) in the lab for making 4x5 copy negatives.
Here's the D.

We had boxes full of those at the lab.
