No it's an FR tank. Came to me when I bought a complete darkroom 2nd hand. It has slots for the film. 4 inch sides top and bottom, 5 inch in the slots. As I always load it the same way, all the sheets in that batch had the same band on left edge. As you can see it doesn't go edge to edge. The tank is not inverted, as chemicals would spill out. I rotate it back and forth, and tip it about 30 degrees, front to back for agitation. Agitate for the first minute, then briefly at 15 min intervals. I've done semistand many times with it, and only previous problem was not enough chemicals to cover properly and had incomplete devlopment at the top.
