Looks to me like a European lens.
Lot of nostalgic fun doing this. Anyone looked at the book on Yul Brynner (a keen photographer) who had lots of camera gear. This one is easy (I am calling a Nikon F with a Nikkor 105mm f2.5.
As is this (an M2/M3 with a Summitar or early Summicron 50mm - more likely the Summicron perhaps given the close focusing distance though that might just have been for effect).
This is a little more challenging I think (The camera looks like a Pentax to me. As for the lens - I have no idea as if it was a Pentax there were squillions of M42 mount lenses available and I have not seen one like this - even the Pentax 300mm lens looks different from my recollection of it).
