Ol' Gabe:
The British tunic and trousers were ordered from "Replicaters" (note spelling), a uniform outfitter located in India. Reviews on the internet are mixed - some folks had bad experiences, but most are positive. Their quality is overall quite good - IF - you give them detailed measurements, descriptions and instructions. Rattlesnake Jack had good results with them for some of his uniforms, and I followed his lead. The more photos and/or drawings you can provide, the better. With my order, we had one mis-fire, but Sanjay made it good at no charge.
The prices are pretty reasonable - I think all together, the tunic and trousers together ran be in the neighborhood of $350. About 270 for the tunic and 80 for the trousers - IF I remember right.
