Having the 8 on 6-1/2 bolt pattern and the # 25580 inner bearing is completely normal, but having the # 15123 outer bearing with this definitely is not. However, the # 15123 bearing will have an inner diameter of 1.25", which happens to be the exact same as the # 14125A bearing. The # 25580 inner bearing and # 14125A outer bearing is commonly found on a hub with the 8 on 6-1/2 bolt pattern and a 5,200 to 7,000 pound axle.
With all that said, the Dexter Trailer Hub and Drum Assembly # 42866UC3 will fit your spindle and is the hub/drum that I recommend for you. You will need to get the # GS-2125DL seal as well though as the included one will be too large for your spindle.
