I've noticed that good WW2 vendors seem to be hiding everywhere. At The Front has passed my searches... until now. According to the Web site:
"ATF has been in existence in one form or another since 1992. We provide exact reproduction WWII uniforms and gear for re-enactors, collectors, museums and films."
So these guys have been knocking about for quite awhile. The site itself is very interesting, and the About page is very informative about the company itself. The goods they produce are presented very nicely, and seem to be fine quality.
At The Front seems to stick with WW2 recreation, but they do have Japanese uniform and gear, and just the usual German/ American/ British mix common with other vendors.
