Cabinets look like Goodmans Magnums, but either I'm wrong or the grille cloth isn't original.
They should have a 12" woofer, 3" cast basket midrange and Philips AD0160 dome or Economax cone tweeter. However, the woofer doesn't look original...can't quite see, but that one looks like it's got an accordian surround (the original has a shiny inverted roll) and the cone colour is wrong. It may have had a later Goodmans Audiom pro woofer chucked in there, or it could be a completely random driver.
Either way, without knowing what the drivers are, I personally would walk away.
