Brand looks like a 'Perfect-10' to me, and they made 7.5, 10, and 12ft versions. That looks like it may be a 7.5, but the 10 doesn't look so different as to easily tell with these sorts of pics. EITHER WAY, it's well worth getting as they are very good signal gatherers...
By the way, IF it is a Perfect-10, I uploaded the manual for it some years ago. It'll print full-size if you want a print, AND it contains assembly and installation instructions for all 3 sizes. Follow them religiously, if you try to put it together like any other dish, it may not work as well! Believe me, I've tried it, lol. Better yet, pull it off the post, and move it WHOLE. You likely will only then have to adjust declination, and plop it on your pole, and aim it at peak to True South, and lock it down.
