Janey that is a Brother built machine. It was probably badged with another name. It looks exactly like a Home Mark machine that recently sold on Ebay for an obscene amount of money. The spool pin design is common for machines that are twin needle capable and came with a pack of twin needles. It's a later 1950's machine. A replacement tension and light switch shouldn't be too hard to find. Unless it's been dropped in a previous life it should be a good machine.
