[Kurt Redinbaugh]

My thanks to Michael Stockhill, Rob Thompson and Ian Williams etal for the
information and the enthusiasm for the Dimona and its aging aches and pains.
I look forward to your continuing support of #3660.

 I had my VDO tach overhauled and repaired in 2015 by:
 Palo Alto Speedometer, Inc.
 718 Emerson Street
 Palo Alto, CA 94301-2410
 (650) 323-0243
 www.paspeedo.com

 At the time, I requested them to keep the hour meter time, and the
 instrument face did not need refinishing, which they also provide if
 desired.

 Suggest a web search to see if they are current.

Thanks for the info Michael. I had sent the tacho to them and they said
they could not determine what the gear ratio (?) of the broken spur gear is
so they advised me to send it to a shop in Virginia Beach, who subsequently
said they couldn't help me and sent the tacho back to mel I have installed
a vibration sense meter and am interested to track it's time shown vs the
actual clock time of engine run.
