Here is the info on the meter.
General Electric single phase watthour meter, type I-30-S, Kh=3, 15 Amp, 240 V.,3 wire, 60 cycle, Model AR5,
On the dial register numbers stamped are 33 1/3.
Accuracy is not a concern, I have never worked on one of these before so just trying to make a cool toy.
If I could get the wheel to spin maybe 20 RPM?
I did try adjusting the S--F screw and it did not have any noticable effect.
Thanks guys, Roger
