I don't know anything about the brand, but if the parts are original, and it looks as though they probably are, then this wasn't an expensive bicycle when new. The chainset and plastic pedals are the sort of thing you find on entry level MTBs and hybrid/city bikes.
It's fine if it's really cheap and you're just going to clean it up to use as a runabout, I have something of a similar standard and quality for popping into town, where I might leave it locked up unattended for a while, so its limited value and thief appeal is an asset. However, I wouldn't buy it as a project to lavish much time and/or money on.
