Bought a Chrondek tree and need some info please

Does anyone know if there is a list or registry for the Chrondek Timing systems ser# or model info, I just bought one that was suppose to be from Riverside Drag strip and would love to find out more about it. Thanks for any help.
Model LS-20
Ser # 133

 

There was a thread on here sometime ago with another gentleman who bought a timing light system that some company had used in their showroom. If my memory serves me correct (I know it won't!) one of the posters did know the history of his light/timing system from the serial number.

Maybe do a little searching it may jump out at you. Good luck with your search. Nice find by the way.

 

I saw that post, but was not able to extract any info from it. I'm trying to contact the son Gary Riley (ollie Riley was the inventor)
