Have you looked on the Lathes.co site? That might both identify it in more detail and possibly give the motor power typical for it.
This neat machine does not seem to resemble the Rollo lathes depicted on that site, and certainly not the Portass I thought it might be, having seen an ad for those in an old copy of "ME".

[My exploration was not made all the more enjoyable by blasted Google and E-bay. They plastered Tony Griffith's display with totally irrelevant ads for industrial packing-machines. After I had marked several as not wanted, Google grew desperate and decided I was looking for fancy lavatory bowls instead.]
