A friend in Canada just send me pics of a New Model #3 that he just acquired. It seems to be a standard target model, but it has an 8 inch barrel, has British proofs and is chambered in 455 and has the longer cylinder. He has slugged the barrel and it measures .454. My understanding is that Target Models were not available in 455. So was this a special order gun with Target sights? I sent him information as to how to get a letter from Roy.
