Assuming the taper is "standard" something-or-other, a live center shouln't be a problem... see www.mscdirect.com or www.travers.com or whomever. Lathe tapers tend to be Morse, although some are Jarno...and a few are weird.
The manual may be another problem. Have you checked www.lathes.co.uk for info?
