Difficult to say from the info available. The ignition switch could well have been moved as it was awkward to get to inside the fairing. The left side handlebar switch looks wrong. Most copies were repainted Honda Britain 750SS, which came in white with either red or blue stripes. These were mostly registered the year after the original PRR came out to get rid of old stock and are generally on a T or V prefix. The PRR are usually on either S or T prefix with a black silencer. So avoid V reg PRR's. I also think that the cover behind the headlamps in the fairing had a different finish. The PRR was smooth whilst the 750SS had a rippled effect to it, but from the piccies I can't really see.
