I have a Triomphe gruppo I'm cleaning for sale. I'm fairly certain the cranks are clear anodized, so it might take some stripping and machine buffing to get them shiny. They are much lighter than I expected, so for 'low-end' Campy, they are much better than a lot of the mid-range Japanese stuff.
I'm not all that clear on price, either, but I think you're probably close to fair market value. I agree with cudak888, however, that you sell the BB separately. I was planning on selling my crank+BB for $45, but that's because the BB is slightly pitted (which I would disclose, of course).
