Not sure about the NES 501B, but the NES 501 I got from Circus Circus in the 1970's says 1.37" high x 0.75" wide x 1.23" long, torque 40 oz/in, speed 0.3 seconds/60 degrees and weight 1.6 ounce. Back then, all ratings were at 4.8 volts.

Thanks for your answer. The servos I have are new but I notice them very slow. I have 2 502 and 3 501 and they all work at the same speed, so I think that this is due to the 0.3s of speed.
Thanks again.
