Hi Jeff - as usual - no primer required by me. Tried it - and I don't like using it. Several light coats of Humbrol paint will be used.
I try for different mixes of shades of brown and black for Cavalry horses usually. Looking at the three newspaper photos I have either dug up - or had sent to me by friends when I was researching the project - looks like mostly the usual darker shades of horse predominate. These could easily be model quality - but I like the Glossy Toy Soldier look - so that's how I want to paint them.
Here's the pic that started it all - with a bit of info attached too. I will give one of the pipers the four inverted cuff chevrons of a pipe-major - as he is specifically mentioned. Good shot of the drums too - with no badges or emblems to be seen. Below that some more pics;
This one's a bit more grainy - but can make them out formed up in fours - and just a peep of a drum in the rear rank
This one was just labled 4 mounted sergeants (not musicians these) - and show the three stripes on the first rider and a good view of the uniform - plus the darkish horses again.
And lastly, the only coloured illustrative picture that I have ever managed to find, which shows two pipers (Clan Shaw Tartan) and a drummer, (again, no badges on the drum). A most useful find, as these are how I intend to paint them - circa 1917.
As a P.S. If anyone has any other relevant pics than these - I would be most grateful for a peek. Many thanks - johnnybach
