Specialized crosstop brake levers.
For 31.8mm bars. Sprung return so they work pretty well. Some of the bolts are a bit rusty but none are siezed. I have no idea what that round plastic thing is. £10 posted please.
Cane Creek SCR-5 drop bar brake levers. Barely used. These cost me £32:
I'd like £17.50 posted please.
