"Victorian Science Fiction cavalry flags" Topic

I'm working on a large multinational aerial cavalry force for Victorian Science fiction set in 1900.

Right now the Human invasion force will consist of three national or Imperial groups; German Dutch, British and United States.

The US force is three regiments of cavalry, remounted as aerial cavalry. Each regiment will have six landers. All regiments will have a command lander which will fly their regimental flag. The command flyer for the 1st Volunteer Cavalry will fly both the Regimental and the United States Flag. Since each lander will be carrying either a full Company/Squadron each lander will have a guidon.

Still not sure about the Germano-Dutch. What cavalry regiments and flags are available for 1900 era.

I need the various flags in 15mm. Who should I be looking at for these various items?

I would start by browsing through the free offerings at Warflag.com

Five words I'd never though I'd see tacked into a sentence :) But it is TMP.
Look for flags based on Franco-Prussian war,
ACW and the like they did not change much between 1860s and 1900, Who to buy from? not sure but you can manipulate and re-colour 'Warflags' stuff on your favorite graphics suite.
Cheers hope that helps

Thanks Chris! Zargon you need to get out more. That is by far not the strangest title I've posted to TMP!
