The Ganesha hilt on the top picture is from Cirebon (I replaced it) and the mendak was replaced also so they are not original.
In the two photos you present it looks as though the mendaks are different and possibly even the hilt. The stain looks better on the on presented on white background. Is the blue background shot then this keris as you recieved it and the white background after hilt/mendak replacement and a cleaning?
