I only do it for the free drugs
Just drink the turps. It will do the same thing for you.
I think you did as good a job as you could, mate. Though did you ever repaint those gunners' shoulder cords (I'd have left that as buff because the others were "only for parades").
The problem with getting good uniform info for the Reichsarmee's smaller contingents (or even some major nations' uniforms) is that some of the "authorities" grabbed whatever evidence they could find and didn't question it. So a portrait of an officer showing light straw facings and a greenish-blue coat is accepted as correct- because they don't stop to think that everything in the portrait has a yellow cast due to the varnish ageing. Then there's detailed regulations that don't agree with orders placed with suppliers. I don't know where Fred gets his info, but I wouldn't be surprised if he has contacts with the museums in Karlsruhe, Ingostadt, etc. He's a good bloke and it's a pity he left Kronoskaf, though I understand why.
