Looks great! I have not seen one commercially available, or Pine Tree flag, just Gadsen and Moultrie.
There is a historical flag site online that has the Pine Tree one and other historical flags. I got Christopher Columbus’s, too - with F and Y on it (Ferdinand and Isabella). The Bedford Flag is very nice.
cb,
The folks at Colonial Flag in Salt Lake City have it on their website (http://www.colonialflag.com/bedford_flag_p/fhbed.htm).
I think I also saw a couple of Pine Tree designs. Look under their Int’l, State, & Military link.
