Imperdix kindly provided photos and of his converted Horsley no. 1547 and information on the conversion. He observes it is probably a later conversion, noting that the top front edge of the lockplates have been filed away to accommodate deeper fences, and that instead of adding a faceplate, Horsley installed a different action frame, something that David Baker believed Horsley did a good trade in, judging from the number of conversions.

It takes a sharp eye to spot some conversions.
