This is a picture of FN3 French Line Grenadier Firing. I picked up both of these figures from the same source but I suspect that only the one on the left is a genuine vintage Hinton Hunt figure. The figure has the HHF mark and FN3 code on the underside of the base which, as far as I know, was the case for all the figures made by Hinton Hunt Figures of Taplow.
The figure on the right was probably made later possibly from a mould made from an original figure. It lacks the same level of detail as the original and the metal is thicker in places – particularly on the shako plume. There are no markings at all under the base which suggests it is a later production or possible bootleg.
However, it may not be as simple as that as there is a fair bit of variation in quality even with the original Hinton Hunt figures. My Prussian Napoleonic army contained distinct variations within the same figure type (presumably there were several different production moulds in use at the same time) and not all castings were of great quality – however, the original figures did all have the HH codes under the base.
As I am a bit anal about having only vintage figures in my new HH army I probably won’t use any of the dubious figures unless I am short of numbers to make up units.
