Brunton Stalker Wiper Arms

[Eclipse19]

Does anyone know what wiper arm would fit these spindles on a Brunton Stalker M Spec?  
 

Thanks

I would expect an mg or triumph snap on arm with a cable drive system, but the splined od ferrule (held on with a set screw to the shaft) that the arm snaps on to is missing.
