I have a Fujinon CM-W 180/5.6 in a Copal #1 available in EXC condition for $395 including shipping in CONUS.
It's an almost-symmetrical design of six elements in five groups. It takes 67mm filters.
Here's a schematic drawing of the lens: http://www.mayadate.org/pix/Fujinon_CM-W.png

This is the later EBC-coated version with lettering on the outside of the barrel.
The IC is 260mm @ infinity (8x10 diagonal is 325mm), so it will cover a range of close-up work, not just 1:1.
It would even work @ infinity with vignetting of the corners.

FFL is 170.7mm, so 1:1 requires a bellows draw of 170.7+180 = 350.7mm (13.8").

I can provide photos if you're interested in it.
