The barrels of the guns were painted with GW Dwarf Bronze, given a very thin wash of alkyd oil-based Burnt Sienna, and then the bronze was touched up on the upper-most parts of the barrels. This seems to add a bit more depth, texture, and visual interest to these relatively plain castings, though that is kind of hard to see in the photograph below.
The conversion, if you can call it that, took only a few minutes of careful trimming away of the officer's sword, followed by drilling the remaining hand out with a pin vise drill and tiny bit. It was then a fairly easy thing to slip and glue the flagpole/guidon assembly into his doctored hand for later painting.
For my standards and guidons, I usually just find interesting stuff online, save it into a file, re-size, and print it out. I then cut it out carefully with a sharp hobby knife and a metal-edged ruler before attaching it to the flagpole with plain old white glue (Elmer's) . I use a small paintbrush handle to add some curls and furls to the standard or guidon and set the entire figure aside, so the glue has time to dry. Later, it's simply a matter of painting in my own colors and central designs over the patterns already on the paper.
Incidentally, the Minden castings are so clean that little to no preparation with a hobby knife is required before you can apply your basecoat and begin painting. How far things have come in just the last 25 years, to say nothing of the last 40! As I remarked to an acquaintance yesterday, Mindens are a bit pricey, but worth every penny given the high quality of the sculpted master figures and the castings these yield. Even if your wargaming pocket is not particularly deep -- and mine is not at the present time (funny what child or two will do to that!) -- treat yourself to a few of these delightful miniatures at some point. Maybe some mounted officers and a few more on foot for a vignette of mid-18th Century generals?
I read somewhere during the last two-three years that the late Peter Gilder tried to achieve a porcelain figure-like appearance through his painting and (shiny) varnishing methods. It's doubtful, of course, that I'll ever approach Mr. Gilder's, or Doug Mason's, level of skill with the brush, but it's what I have in mind whenever I sit down to the painting table these days.
Speaking of cavalry and, more specifically, horses, every wargamer who paints figures larger than 2mm-10mm should have at least one good reference book on the beasts in his or her library. One that I have found invaluable in the last five years has been Horses (1993) by Elwyn Hartley Edwards, part of the Smithsonian Handbook series. Very briefly, it contains all kinds of information on the various recognized breeds of horse around the world, their history, breeding, development, anatomy, and -- significantly for painters -- high quality photographs, which provide accurate representation of the true colors and shades of the horses' coats. Moreover, Edwards' handbook is a convenient size to use at your painting table, measuring just 15cm x 21.5cm.
There are many other books on the subject available, but these suffer from two ills. First, many are coffee table-sized, which means they are large format. While this is in no way is a bad thing, it is difficult to use such books comfortably while you are seated with a bunch of primed figures and open containers of paint lined up on the painting table before you. Second, many other horse books are clearly aimed at that peculiar subset of the female sex, the horse-obsessed girl under the age of twelve.
Now, there is NOTHING wrong with that. And in fact, my own sister suffered from the same affliction for a few years. Keep in mind, we actually had a few horses at the time, but my mother and I were much more responsible for the considerable upkeep they required. It's a hell of a lot of work caring for horses! That's another story though.
Returning to the subject of books on horses though, the kind I am talking about in this second instance don't necessarily provide the same kind of information useful to wargamers, or serious equestrians, beyond some of the photographs contained therein. So, if you are in the market for a handbook on equines, you could do worse than Horses by Elwyn Hartley Edwards (Catsmeat Potter-Pirbright anyone?). The price is right too, It currently retails on Amazon.com for just US$ 12.95.
