If its the look you're going for the specific brands of the parts aren't hugely important.

The Stem looks like an AVA, like what's on some early70's Peugeots. The hubs are High-Flange. Possibly Normandy , or Campagnolo from the cutouts.

I don't know about the handlebars but you could probably use these http://velo-orange.com/niprha.html flipped and with the grip area chopped down a little.
