Thanks all for your suggestions. I don't like the Askari ones, these are awful sculpts. I think I'll go for Perry's, although the poses are a bit stiff and static as usual. I would have liked some more dynamic poses, like firing the gun, aiming, loading, not just standing around.
Anyway, another option would be to go for a Naval Brigade crew with figs from Copplestone or Perry.
We'll see ...
