Obviously it was made to use those shutter speeds even though by the "1 over focal length" rule these would be too long for handheld use.

Old folding MF cameras (particularly from the cheaper end) were expected to produce contact prints in the main. Our family photos from the 1950s are all 6x9 prints - ie contacts - at that size, camera shake is not so visible.
