Further questions;
Would Foundry's FPW French gun team fit in with later colonial troops?

Dear "a_i_42" 
I'm not a specialist of artillery matters so I really don't know : I just think they are nice figures and highly usable in a "fictiounous" context 
Cool, I think these are what I'll go with then. I would've bought Brigades, but I'm looking for a smaller gun than the 75.
By the way, what do you mean by "later" ?
Not entirely sure, but for the sake or argument lets go for 1880-1900. Ish.

I know you are not too keen on Askary miniatures, but it makes a nice pair of mountain guns : the colonial artillery were often old "recycled" pieces.
I'll bear that in mind. I didn't know if there was a standard gun or, as you say, they simply used old pieces. I'll probably go with an old muzzle-loader if this is the case.
I'm very curious to know why : I have always been intrigued by their italians.
Yes, the Italians do look quite good. The figures I bought, however, are quite horrendous;

This is, apparently, an Arab carrying a water bucket. The poor fellow doesn't even look human...
Thanks for the reply, matou, it’s been very helpful (as always). I must find a reference book on French colonialism...
