Really excellent progress. And put together so fast! That jacket is gorgeous, and your modified pants turned out a lot better than mine did. I finally broke down and bought some real ones this week.
I got most of my web gear - suspenders, cartridge belt, and map case strap - from At the Front because I'd had good experiences with them in the past and they have all the correct gear but offer budget versions of a few things. They have the compass pouches and general purpose strap too, but I got mine elsewhere (I can dig up the name of the eBay store if you'd like). I think What Price Glory and WWII Impressions have all or most of the correct gear too, but I've never ordered from them so I can't speak to their quality. And if you have a surplus store near you, you might find something that works there.
