This has nothing to do with "research" per se....
But I was surfing the web some time ago and I came across a unit with an excellent webpage that showed the transitions of the uniforms in North Carolina (prewar-late). It really impressed me! Needless to say I can't remember the address for the life of me and I was wondering if anyone had their link.
All I know is that this unit also does dual impressions....thats all I remember!
