Need Help with my new Camera (Baldina)

[super june]

I have received a Baldina Compur-Rapid, that belonged to my grandfather.

And it would be great if someone could guide me a little... it would be great

and first, i would like to know how to put a film inside my camera... i see a small lever with an arrow, but it won't open anything (sorry for my lack in english)

note: my camera seem to be in a quite bad condition. it is a bit rusty, though it was in it's case.
