As Bob says a Linhof Master Technika. This is a field camera that makes 4x5 inch film negatives. In your case you also have the 9x12 Techno Rollex back, a very pricy item, that shoots panoramic 9x12cm negatives on 120 roll film. This model first came out in 1972 and is still sold by Linhof today as the Master Technika Classic. The camera is capable of view camera movements, tilt, shift, swing, & rise. The ability to close up like a turtle in a protective shell makes it ideal for travel and field use. It can even be fitted with a hand-grip and used as a hand camera if you have strong arms! Most of us will use it on a tripod which allows more time to make critical decisions in composition and camera settings. Your camera looks to be in used but good shape. The camera in the photos has the bed set to accept 3 lenses, as it has 3 infinity stops and 3 focal lengths indicated on the focus distance scales along the side. This camera also has a rangefinder for focus which is nice and somewhat unique on a view camera but it needs to be calibrated properly to each lens via a butter knife shaped cam.
