Sorry to be of no help on ID'ing, but....
I ride full fenders, F&R, with flaps.... and I still get soaked in the rain after 30 minutes riding. That thing is too short to protect your back from the brown spray that will kick up off the back tire. It does not extend down far enough to keep the backs of your ankels and drive-train from getting a bunch of gunk and crud strewn on it.
It will however keep 1/3 of your seat tube and the underside of your saddle free from dirty water.
No ill will intended, just realize it will do almost the same as not having no fender at all.....
