I am looking for a belt buckle of the California State Flag to
purchase.  I have found California belt buckles depicting the golden
gate bridge, the California state seal, and other images related to
California.  I am not interested in these.  The belt buckle I am
looking for will be the shape of a flag, in color (white with brown
bear in center, red star above bear and red strip on bottom, with text
of "California Republic" under bear), and made of metal (possibly
pewter).  I have searched for this belt buckle and have not found it
but would like to purchase one.  Somebody somewhere must have produced
a buckle like this.

I keep seeing this pop to the top...  I have looked, can't believe
they are so hard to find. One would think that would be a common item,
but no!

I know it's not exactly what you were looking for, but it may be your best bet.
