I have an Augusta batroom sink with a two handle, single hole faucet assembly. There is no manufacture name on the assembly but it looks just like the "Fima Frattini" Nameeks S5041 with dome handles. The handles are mounted at 2 and 10 o'clock into the base of the faucet. There are no access holes in the handles for access to locking or set screws. How are the handles removed ???
