Early to mid-19th century, probably dating to the Mexican-American War of 1842. Typical heavy proportions with slightly recurved 23" wedge section blade. The dropped point of the fashion popular at the time and most notably preserved on the Bowie knife. Iron D form guard with slightly down turned quillon. Two piece slab sided wood grips. One with a large splinter and both with typical dry surface degradation. Hilt and blade with glossy chocolate patina mixed with old arrested rust growth. Classic Texas/Southwest colonial example.
