This is a gorgeous belt plate! It is the belt plate from just after the Civil War. This buckle is like the buckle that is illustrated as figure #370 of the buckle book on page #237 in the Civil War belt Buckle book by Duncan Campbell and Mike O'Donnell. They state that this plate would have been worn by the New York militia group known as the "City Guard Reserves" and would have been made about 1875 until around 1900. It has the beautiful applied silver metal numbers in the center. It makes a note in the book that this ornate
post-war stock pattern with thick belt loops, oak-leaf wreath with four ridged
cross-ties and flat back. This example belonged to Brooklyn's CITY GUARD
RESERVES, organized as the 23rd Regiment in 1862. It may date from 1869 when
they adopted new dress uniforms. A quantity was found during the 1960s after
the Cleary Uniform Company of Brooklyn closed its doors. Cleary had earlier
purchased the Ridabock stock which dated back to the 1880s. This is a gorgeous buckle that displays superbly!
