How 'bout a couple of decent pix of the front, the side, the back, etc?
If it's an OEM , I'm sure someone will be able to identify it for ya.
If there is a motor, take a couple of shots of that, how it mounts, and where it attaches.
Likewise, take a peek under the LNB cover if you can get it off (watch out for bees or wasp nests) and shoot some pix there, too.
Make sure the photos are in focus - don't get too close.
