Hi.
I happened to see your question and it reminded me of this 600 page supply book someone mailed me (probably from some magazine subscription...) and it has tons of parts:
www.outwater.com - 'Architectural Products by Outwater LLC'.
I haven't checked their web site, but there is 5-6 pages of steel, brass and wood 'bar rail' parts around page 230.
