Sorry, I don't have one.
But I do know an alternative.
Way back in QST for March, 1971, there was an article about a line voltage
and frequency monitor. The frequency measuring section consists of a couple of
resistors, a pair of zener diodes, a 0.22 uf capacitor, a bridge rectifier, a
calibration pot and a 0-1 mA meter. I built one and it works very well.
