That's a Top Gun, the UFO come with the lenses. I love the UFO undertail, but couldn't never find them. It's very hard to find those undertail, I got lucky and found two Top Gun on Ebay one I'll keep it as a spare. I couldn't find the lenses so I made one. What I used was from a fluorescent fixture lenses cover that I've found. I traced it out a little larger and I used a cut off wheel then grind it to shape about 1/8 larger all around. Put it in the toaster at low temperature, too hot too fast will make it turn brown. I used the bowl or you can find something that has the same curve as the undertail. When it's ready put it on the bowl and hold it there till it cool down and don't forget to use a smooth side facing out. Now slowly grind it until it fit then use clear silicone to hold it place.
