When was the California Bear Flag first made?

Exactly when was the Bear Flag created has been a matter of some dispute, complicated further by the issue of what was the "original" flag.

What we do know, without too much dispute is that Sonoma was taken by the Bear Flaggers near dawn on 6/14/1846. We also know, almost certainly, the flag was made at Sonoma after it was taken.

We also know with certainty that the flag had been created by noon on 6/17/1846 because Lt. Missroon of the Portsmouth saw it by that time and officially reported in writing about the Bear Flag's existence in Sonoma.

This would seem to mean, with a fair amount of certainty, that the Bear Flag was first made between c. dawn 6/14/1846 and c. noon 6/17/1846.

At some point in those 77 or so hours the Bear Flag was made.
