i hate making assumptions, so i'll take a guess an say that you are asking if this is an '89 reverse?? if so, no, does not look it to me. if its something else your asking, then sorry, my mind reading skills are not working...
You are gonna have to clear up the photo. It looks to have a flange but it is too pixelated and out of focus to tell. Magnifying the photo is not working for you. Get as close as you can with out magnifying and shoot, crop and post. move some lights around, it is too bright.
there is no bottom serif, the end of the top arc of the "G" lines up with the vertical bar, the "F" is not tilted = '88 reverse
I'm lost I thought the f should not be tilted and its closer to base fatter ikk take better pic I guess
