It looks like an early version of the AWVSL900 but it doesn't look like the head can swivel. As far as I can make out the acronym stands for Axminster Wood Variable Speed Lathe or Axminster Wood Variable Swivel Lathe and the 900 is the capacity between centres.
I agree with phil.p though, it is probably worth sending the photo to Axminster. Pretty sure though the spec will be very similar to the current hobby lathes, and spares will be compatible.
