A somewhat late reply, but here goes; the second lathe is a Denford Viceroy, which turns 5" x 24". I've got one just like it; the one in the picture is more or less equivalent to a Boxford AUD; power feeds both ways and a norton type quickchange gearbox. The going rate on ebay for one with some tooling is about £500, but I stole mine for the price of a good curry and a night out. http://www.lathes.co.uk/ will tell you all you need to know.
