If your bars are 23.8mm diameter (with bar end brakes, I would be surprised if they are not), then there is a nice brand new set of classically styled Velo Orange brake levers for sale on the C/V sale forum here. I'm not affiliated with the seller, but I have a set of these levers and like them. It's an inexpensive alternative if you need them.
