Cast Eagle buckle tongue with 27 stars encircling the perimeter. Circa later 1840's through 1850's. The matching outer wreath for these particular Tongue & Wreath buckles, (or clasps as these were generally referred to during the period), is smooth with no design. Possible of course that these were used by some militia units, although from numbers of recoveries across the country, the vast majority have surfaced from non-military sites. Most likely commercially available on belts during the time, for use in carrying the popular Bowie knives and pistols. Daguerreotype and Ambrotype photographs of the 1840's and 1850's are noted with gentlemen wearing civilian clothing, sporting similar belts with Tongue & Wreath Eagle buckles/clasps.
