There you go trying to make sense of things fifty years later.
I'm not saying that yours could not be original just that that the findings are not the nor or typical for the time period. See you've gotten input from cars through out the year which can be misleading IMHO. As stated earlier I'm cool with you using what you found. The rest of the exercise has been in response to what San Jose typically used and when
Haha, yeah, I know what you mean, this is a tough game sometimes to try to make sense of these things, always appreciate your input and knowledge on the subject though, it always helps...
Thanks,
