Hi TC. I had the Alamo Searles in mind. Simple cross guard. It was given to a Capt. Fowler of the U S Dragoons I believe in the 1830's or early 40's. He was stationed here in my home town at Ft. Mellon for a time during one of our Seminole wars, and as I recall, he would have had possesion of it at that time. It has been in the Alamo on display for many years. I have seen photos of at least two others like it by Searles, but they are not as large or well preserved. I have no idea about the Seguine Bowie.
