My first batch will be in the old Saumur kepi; some units blue kepi and others kepi with white cover - uniform dirty white.  This was the basic Porfirista squaddie, but when the "WW1 look" with peaked caps came in many units were still in the old gear -a bit like the 1920 Polish army you would find units in various stages of transition depending on where you were and how quickly supply was coming through.
For a second batch I'll move to the "new look" Huertistas in peaked caps, not forgetting to add some of the (apparently universally hated) Rurales ...

Been re-reading my Osprey book on the Revolution, where we find that in the (woebegone) Porfirista army a normal allocation of 100 rounds per man was reduced to 50 because the badly-led and under-trained conscripts had a tendency to blaze away wildly and waste ammunition.

Hi Martin - yes, very keen; and I will be getting an initial order in shortly.
Of course interest began with Spaghetti Westerns and whatnot when I was a lad (a long time ago), then eventually the period became something I wanted to read books about and to wargame ...but until now I've done nothing about it, more conventional periods taking my time up: that and the relative dearth of suitable available figures.
There are some larger scale options, but 15mm is perfect if you want impressive numbers of Villista cavalry, etc.
Some of your contributors have already spotted plenty of PP items they can already use - some obvious, some not so obvious, like the WW1 Serbian armed women, who are I think ideal (with a paint job that hood becomes a mantilla).
I hope the range, as it develops, does well - and that just maybe you might eventually consider adding a couple or three buildings: for some reason Hispanic-style buildings are hard to find in 15mm, although for the basics there are adobe N African buildings that can easily be converted; but some Latin buildings with terracotta roofs, and particularly a classic Spaghetti Western church, would be ideal - and would have masses of different potential uses, either adding to the pirate range or being used for the Peninsular War etc.

If you have this book and the Osprey book you are off and running for the Mexican Revolution - a superb read.

For film inspiration (apart from the 1960's/70's stuff, of which Villa Rides is easily the best) I recommend "And starring Pancho Villa as himself", a 2003 TV movie which has some superb and harrowing action sequences: if you search "Battle of Torreon" on Youtube you will get that particular excerpt.
The crazed American machine-gunner (MG mounted on truck) is completely accurate and was a real-life character: fully described in the Frank McLynn Villa and Zapata book (which again I heartily recommend: it tells the full story of the Revolution years in a very accessible and intelligent way).

While the US involvement was confined to Vera Cruz and the fruitless Pershing expedition the planned US figures are actually quite useful, as the Carranzistas wore versions of US kit - as did some Villista units, for example the Juarez Brigade shown in the Osprey book: I suspect the appearance was a semi-motley "Confederate" version of the US kit.
In the excellent Villa and Zapata book by Frank McLynn he relates how a Kelly-s Heroes-style racket saw trainloads of kit intended for US forces in Texas being condemned as "soiled", whereas in fact it was reset to the Villistas at knock-down prices.
Apart from buying PP Yanks perhaps they will bring out heads with Montana hats, as an additional option.
