The Los Angeles Times ran an article in 1948, (or 1949, my memory is vague on which year) that described a Kentucky Rifle owned by an elderly woman in Lancaster, CA. Best I can recall it was a Lancaster, PA gun, and that it was said to be an Alamo rifle.
She told the story that her family owned a farm in MO and often hired men to work there. One day, a Spanish speaking man came by carrying an old fashioned rifle. He was hired on,
stayed, and almost became a member of the family, over the years.
Shortly before the man passed away, he gave the rifle to his benefactor and told the story that he had been conscripted by the Mexicans to fight at the Alamo. After the battle, he picked up the rifle and returned to Mexico. He kept the gun and brought it with him when he eventually emigrated to the US.
There was no claim that it belonged to Crockett. Last I heard, a prominant west coast collector was investigating the matter and that is where it ended. The collector was well qualified to do it as he had at least one Bowie Knife and other items that had been found at the battle site.
The rifle in the Alamo Museum is a plain gun with a daisy patchbox and said to be a Dickert gun. Many feel that since it is plain it can't be the original stock. Another plain Dickert is owned by a collector in Colorado that has Rev. War history, but also has been decried by many as just another restock. Every rifle made by Dickert (et al) can't have been a work of art piece, in my opinion. Even the best of the makers built some pretty standard, working guns that lacked the carving inlays, and so on that today typify a KY Rifle. Just some random thoughts and memories harking back 65 years, or so.
