Contessa Nettel Deckrullo

Today I held a Contessa Nettel Deckrullo (I think) that was from a old photographer of my home town and is one of the cameras of his legacy that the city museum have. Besides me and other two people, we could not find how to set the camera in B or Z/T.
Anyone here knows how to do it, or is the manual in the web? I shearched but could only find sites about the camera but not explaining how to work with it.
Of course that the museum persons think that the camer is working fine, but do not have certain.

As it's a focal plane shutter you'd have to reset the shutter curtain, usually theres a tension setting and a slit width setting and the combination gives you the final speed. It's usually T rather than B and you use it for focussing as well.

So for T it's set so the cutain opens and stops on the first release then closes on the second.
