Help needed with a san yuen lathe

[Hogmd]

Hey guys I am new here and looking for some info or manual of some kind for a old san yuen lathe it is roughly 15x40 gap bed lathe I think is from the mid 70s. I have attached a couple of pics. She has a new coat of paint on her. I think the model is a 1550 mm or that's the size not sure any info would be much appreciated. Thanks
