M is for Master Figure

This is an odd one, it's 'believed to be', so not 100% accurate, which is not the best start, but it is a lovely figure, which deserves a horse, and painting, but if it is a Master Figure, it should really be left alone, however, I can't find it in any of the HM of GB catalogues, flyers or colour post-card type things I have in the archive, so . . . Can anyone confirm this as an HM of GB sculpt?

 

There are three parts, an ornate sword in sheath, a head & torso and legs/saddlery, and I think -from the jacket/frock coat - that he's from the Indian Raj period, but he could be a Janissary or Marmaluke? Although I don't think HM were noted for the latter periods, but they did cover the Egyptian campaigns, and a Jubilee procession?

 

The two halves assembled.

Believed to be sculpted by a Nigel Farnhill, for HM of GB, it's fashioned from a hard material, possibly the two-part epoxy, neutral grey, Milliput, with hints of a wire armature, in addition to the locating pin.

 

Was he an extension, or planned extension, to the On Foreign Service range, or something more Delhi Durbar related? If anyone can add anything to this less than informative post, that would be great, maybe the sculptor's right, but the figure ended-up in another brand's range?
