Lathe No 1910, a rose engine 'conversion' (i.e. with a limited range of capabilities compared with a 'full' rose engine) was supplied to William H. Campbell of Berwickshire in 1847. No 1909, also a rose engine conversion, was supplied to Sir Hugh Campbell at about the same time, and was probably very similar, although the headstock alone survives and is not identical in every detail to that of 1910.
