I found a set of Triomphe levers mostly for the gum hoods in a bike shop in Mesa AZ, I think for around $35 the pair. They appear to me identical to late NR levers excepting the shield logo instead of the script "CAMPAGNOLO". I have the levers on my Bartali now and they look great and I'm not the least bit nervous about scratching them.
Good deal.
