Self Steering Rudder

[Wandering Star]

Have no connection to the seller but noticed this eBay auction which I thought mght be of interest to one of you rufty tufty liveaboard sailors. http://www.ebay.co.uk/itm/SELF-STEERING-RUDDER-/162178505963?hash=item25c2979ceb:g:j50AAOSw-itXvJPJ - it mentions Sirius but I think it looks very similar to an Aries rudder though I mght be quite wrong.

It would have helped if the seller said what it fits.

It would have helped if the seller said what it fits.

You mean like this:
"SHED FIND
RUDDER FROM WHAT I BELIEVE TO BE
SIRIUS SELF
STEERING GEAR MECHANISM"

The OP suggested it might in fact be from an Aries.
On the other hand, it could be a servo oar rather than a rudder.
