Brunswick bewilderment

I bought these guys as 'Brunswick Avante Garde' on ebay, clearly not Hinton Hunt, maybe Minifigs S range? Any info gratefully received. On temporary bases at the moment pending any re-touching/re-painting.

And the officer looks more like a later Minifigs 25mm casting. So much taller than the other ranks, I guess I can justify this by the fact that the officer corps would have been better fed than the peasants recruited from the forests and mountains for the Jaeger corps. They are painted in a quite dark neutral grey/green so I guess they could qualify equally as Waterloo period  Avante Garde Jaegers (both types) as well as Peninsular period Oels Jaegers.

I always thought the Black Brunswickers' early history would make an interesting wargame campaign. A fighting retreat across northern Germany to the mouth of the Weser where they were embarked by the Royal Navy before entering British service. Shame about their subsequent poor reputation in the Peninsular (famous for rate of desertion, probably due to the fact that replacements came from German/other PoWs and better quality recruits went to the KGL). But they seem to have redeemed themselves in the 100 days.
