Both belonged to my cinematographer father (JohnMcLean ACS), and to Frank Hurley (Sun newspaper reporter) before him.
I'm very confused about which models they are, I can't find ANY serial nos on either of them.

Please see the pictures attached The first is #1 camera, the second pictures are the #2 camera.
The first camera is much smaller than the second.
if there are any features I can describe to you that would help, let me know. I don't know my way around them well, but will try.

Many thanks,
Jenny.
