A Russian 1799 range is announced by Trent and the first pictures are up on their website so let's see how many they will bring out of these before they wander off to another topic.Old Glory ( http://www.oldglory25s.com/ )
As I haven't seen them in the flesh (or better metal), if you are interested you better order some (although I don't know if that is possible with Old Glory packing ideas.
Probably also some Napoleonic range figures (eg early French in bicorn) are usable for the French revolution.
Other pictures of Old glory ranges (although in black and white and sometimes not very clear) can be seen at http://www.oldgloryminiatures.com/categories.asp?cat=13 .
On the Egyptian campaign topic, Dixon also offers a range for this period; but now only French troops.
The French infantry are in the Kleber (short) coat plus in the longer (let's say European) coat. These last ones also usable eg in Italy.
It's a shame that no pictures are on the website.
Dixon also offers a Ottoman Turk range of whcih some fgures could be drafted as adversaries to the French.
The Ottoman troop look very nice on the website pictures (left)
Redoubt Enterprises ( http://www.redoubtenterprises.com/ ) has another colourfull range namely "Wellington in India"
Unusual uniformed troops and very colourfull, these troops would grace any wargames table. Seeing some elephants in 25mm always is a joy for the eye.
The only drawback is, that the figures are very big; at least they looked that way when I saw them some time ago.
Maybe that newer figure ranges of other companies, who are also more in the region of 30mm, let them look something smaller.
Sadly, no pictures on the website, only some drawings of some of the offerings.
