I do indeed. It was conserved a few years ago however (as it was "found") - the flag of the New Orleans Grays - and looks beautiful. There is an article on the flag's conservation in the catalog of a textiles conference held in New York some years ago (ten or so) with a B & W picture of the conserved flag.
I suspect that the flag was hidden rather than lost because it was such a high value banner. If you look in the Mexican flags book you will note a red banner in it. I suspect that this may be the flag of the Alabama Red Rovers who came to the Alamo but cannot prove it.
